Early Television Museum
CRT Rebuilding Project
The last remaining picture tube rebuilder in the United States, Hawkeye, closed its doors in 2010. RACS, the last rebuilder in Europe, ceased operation in 2013.
Now that they are gone, there is no place to get tubes for vintage TV sets rebuilt. More importantly, the techniques for rebuilding these tubes will be lost forever. Here is other recent activity on CRT rebuilding.
Several collectors have expressed an interest in finding a way to keep rebuilding alive. Scott Avitt, who owns Hawkeye, has indicated that he would be willing to donate his equipment to the museum, and to teach people the secrets of rebuilting tubes. The museum has the space for the equipment. The goal would be to move the equipment to Hilliard, install it, and to rebuild vintage tubes for collectors. Whether this is possible depends on several things, among which are:
1. Finding a person or person who is willing to devote the time to learning the process.
2. Finding people who will coordinate the project, both now and in the future.
3. Raising the money needed to get started.
4. Solving economic issues. On the expense side, the cost of insurance, utilities and supplies must be considered. On the income side, we need to understand what tubes can be rebuilt at a cost that collectors are willing to pay.

The painting is finished, and today we moved the equipment in. We still have workbenches to build, shelves to install, and the gas line to connect. Thanks to John Estep for his help today. The next project is building an oven. We will wait until John Yurkon is finished with his project and then build an oven similar to his.
Progress Report, July 12, 2014
Walls and ceiling of the CRT rebuilding room have been painted. Next is the floor. We will schedule a day sometime this summer for volunteers to install the equipment and finish the construction.
We are still waiting for details of a quote that RACS received for shipment of their stuff to Ohio. We expect that shipment will happen this summer.
Progress Report, May 23, 2014
Several volunteers worked on Friday before the convention and Monday after to finish the drywall, electrical and plumbing. In the next two weeks we will install the trim, and paint the walls and floor. Then we will move the equipment in. Another volunteer will be here soon to complete the gas line.
We are stilll waiting for more quotes on shipping the RACS equipment, and for a list of items for customs. Once we have those we will select a shipper. We expect to get the equipment sometime this summer. Basically the RACS equipment will allow us to do phosphoring and aluminizing.
The remaining item is the oven. John Yurkon will design an electric one, large enough for a 30BP4. Once we have an estimate of the cost, we will solicit donations to pay for it.
Progress Report, May 5, 2014
We have now raised enough to purchase the equipment from RACS and transport it to the museum. We are in the process of getting quotes for delivery, which should be in about a month. In addition to the equipment, the dud 15GP22s that were sent to RACS by collectors will also be shipped. Thanks to all who donated. Special thanks to Jerome Halphen, who has generously offered to purchase the RACS equipment (5000 Euros, about $6,900) for the museum.
The CRT room is now ready for drywall finish. Volunteers will do this the day before the Convention. Volunteers will also finish the gas line, water line and electrical wiring. Shelves and a workbench will be constructed, and the equipment from Hawkeye will be installed.
The final item is the oven. We plan to purchase the materials for the oven after the convention.
Progress Report, March 21, 2014
We plan to have the room competed before the convention. That means that the drywall will be finished, electrical and gas roughed in, doors installed, and plywood installed above the ceiling for the storage area. We are scheduling two work days, one before and one after the convention. We hope to have volunteers for those days to:
1. Tape and finish the drywall
2. Build shelves and a workbench
3. Finish the electrical (outlets and faceplates)
4. Install gas and water lines to the room
5. Install the equipment and connect it
If you can work on either Friday, May 15 or Monday, May 19 on any of these things, please contact us.
Progress Report, March 17, 2014
Gas line installed, door to shop area installed, most of the electical done. Drywall is on half of the ceiling, and we are starting on the walls.
Progress Report, March 9, 2014
Now that I'm back in Ohio for a few weeks, I can return to work on the CRT room. Today I did about half of the ceiling drywall. Tomorrow I plan to complete the electrical wiring and install the gas line for the equipment and the space heater. Later this week I hope to complete the drywall.
Donations continue to come in, including a $50 a month recurring one from Matt D'Asaro. We have a balance of about $1,400 in the fund.

Framing is now complete, as is most of the electrical work. We started on the ceiling drywall today.
Progress Report, December 1, 2013
Framing is now almost complete, as is some of the electrical wiring. We expect to start drywall hanging this week. We have received two generous donations recently - $200 from Steffen Demos and $1,000 from Ralph Sargent. These should be enough to pay for the materials to complete the room.
We still need to buy materials for the oven (probably around $2,500), purchased whatever guns, cathodes, heaters and getters we can find, and possibly ship some equipment and supplies from RACS in France, which has shut down.
You can help by making a donation to the rebuilding project here.
As of two weeks ago. Since then the ceiling framing has been completed.

Layout of the new CRT room
More framing progress. Walls are done and we are starting on the ceiling. The space above the room will be used for storage of supplies.
Progress Report, October 12, 2013
Framing going up. the room will have two doors - the framing for one is shown, the other will be on the end at the right. It will use the existing concrete floor, and will be about 8 ft. high, finished with drywall. The oven will be outside the room, on the right wall. You can see the vertical lathe (behind the ladder) and the horizontal lathe (far right). The area above the room will have plywood on top of the ceiling beams so that CRTs and supplies can be stored there. The stage (foreground) will be re-assembled next to the wall when the room is finished for future conventions.
We purchased a large number of guns and other materials from a person in Washington state, and had them shipped to Hilliard. The CRT rebuilding fund has $887.17 remaining in it. That will pay for a portion of the cost of building the room (total cost about $2500). We will need additional money to complete the room, build an oven, and buy supplies such as guns, stems and getters. We will be soliciting donations for all of this in the near future.
Progress Report, September 4, 2013
The CRT rebuilding project is finally underway. We have begun work on the room to house the equipment we got from Hawkeye. The design is slightly different than the one proposed earlier, but will be simpler to build. We expect construction to be completed by the end of the year.
We are trying to accumulate as much stock of stems, glass tubing, guns and other items as we can. Sources for many items, such as cathodes, heaters and guns, are drying up. It is important that we have enough of those critical items to rebuild many tubes. We recently purchased a large quantity of color guns and other related items from a closed CRT plant in Washington state.
All of this is going to cost money, so we will be making an appeal for donations in the near future.

Progress Report, May 16, 2012
At the committee meeting on May 6 at the Early Television Convention, the following was decided:
1. The main problem with rebuilding tubes at the museum remains the lack of a person or persons who will take responsibility for coordinating the project.
2. After Nick Williams returns from France (see below), we will modify Bob Galanter's layout to incorporate whatever equipment we hope to get from RACS. A volunteer weekend will be set up to build the room for rebuilding. Chuck Azar agreed to get a list of those who will volunteer, together with their skills. Steve McVoy agreed to make a bill of materials. There is a balance in the rebuilding account, but it is probably not enough for this project, so additional donations will be solicited.
3. It is hoped that having the facilities set up will encourage someone to step up and agree to be the rebuilding coordinator.
4. Jerome Halphen has generously agreed to pay for a trip to RACS by Nick Williams, who will learn the rebuilding process, take photos, and decide, with the help of Bob Galanter and others, what equipment would be helpful for our effort.
Progress Report - January 25, 2011
Bob Galanter has designed a preliminary floor plan for the rebuilding facility. A room will be built in the warehouse area, adjacent to the present British/European Postwar display room, to house all of the rebuilding equipment except the oven and bombarder. A glass window will be installed between the new room and the British/European Postwar room for museum visitors to view the rebuiling operati

The trailer is now at the museum Bob Dobush finally found a driver who was interested in the job. We rented a tractor from Penske, and the trailer was picked up yesterday and arrived at the museum today. We plan to unload it over the next couple of weeks, then attempt to sell it. After paying expenses for the transport, we have a balance of $1551.42 in the fund.
Progress Report - October 11, 2010
To move the equipment we have purchased a semi trailer from Scotty for $1,000, plus $300 for tires. Scotty has finished loading everything in the trailer. Bob Dobush has contacted trucking companies for quotes for taking the trailer to Hilliard. Timing depends on when we get a price for moving the trailer that is reasonable. But now that the equipment is loaded there is no hurry about gettting it to Hilliard.
Bob Dobush will make a trip to Hawkeye with a van to pick up items that remain.
Once we know the date of the move, we will set a weekend for unloading. We will ask for volunteers who can come to the museum on a Saturday or Sunday to help.
After the trailer is unloaded, it is our plan to sell the trailer. We hope to be able to sell it for about what we paid for it.
Progress Report - October 2, 2010
We have received additional donations, and have had no addiional expenses since the last report. As of October 2 we have a balance of $4,387.61 in the fund.
Progress Report - September 19, 2010
Scotty has generously agreed to donate the equipment, valued at over $20,000, and Bob Dobush is willing to move the equipment (he needs help, of course). We have room at the museum to store and eventually set up the equipment.
Scotty has agreed to sell us a flatbed trailer which will be loaded with all the equipment. Bob Dobush is getting quotes for having the trailer brought to Hilliard. Bob's estimate is that the project will cost no more than $3,000. An appeal to the collecting community raised over $3,400, and the move is scheduled for the end of September. Donors to the fund can be seen on that page.
As of September 19 we have a balance of $3,357.28 in the fund.
Progress Report - May 12, 2010
At the meeting on April 25, Bob Dobush (firstname.lastname@example.org) agreed to be the project leader. It was decided that the project would be divided into two steps. First, arrangements will be made to transport the plant to the museum. The largest item is the oven, which could possibly be cut up and only a portion transported. The second step will be to put together a plan to operate the plant. Many issues have to be resolved, including financing, manpower, insurance, liability and management.
If an workable plan is developed, we will move forward on installing the equipment and operating it.
Several people volunteered to visit Haweye before they shut down for training in operating the equipment. The traning session will be videotaped.
Since the meeting, Bob has learned that Scotty will probably shut down in July, so there is more urgency in making arrangements for the transport and the training session.
