Now available for sale: Replacement for the vertical dynamic convergence transformer for the RCA CT100 color TV. Price $200. I will pot the new transformer in your old transformer housing using silicone rubber for an additional $40.

The vertical dynamic convergence transformer in the RCA CT100 color TV is subject to a high failure rate for several reasons. First, the transformer is would with very fine wire, (#40 and # 43 gauge). This fine wire is subject to damage due to corrosion caused by acids and impurities in the materials used to construct the transformer, and from moisture intrusion into the pitch which was used to pot the transformer. The pitch expands and contracts with temperature, and develops cracks. In addition to moisture intrusion, the movement of the pitch may lead to mechanical failure of the fine wires where they are joined to the larger external lead wires. The failure modes show up as open circuits on either the primary, or more frequently, the secondary windings. While this will not cause any damage to the TV, it will prevent proper convergence, and may lead to loss of focus voltage at the CRT.

Second, is the 3-4KV DC focus voltage applied to the secondary of the transformer. This makes the transformer prone to arcing or shorting from secondary to primary. This can lead to a more catastrophic failure. If a short develops from secondary to primary, all the power from the focus rectifier is dissipated into the focus potentiometer. And if the wiper of the focus pot is near the high potential side, all the power is dissipated in a small portion of the resistive element of the potentiometer, burning it out in a matter of only a few seconds.

I have seen several convergence transformers which were open circuit at the start of a CT100 restoration, and have witnessed two transformers short out after the set was restored and powered up, resulting in the destruction of one focus potentiometer. This is what has inspired me to take on the challenge of having a replacement transformer built. These transformers have been installed in several CT100 TVs, as well as Westinghouse, Silvertone and Sylvania 15" color TVs.

So you 15" color TV owners may want to consider one of these replacement transformers. Supplies are limited, with no assurance of future availability.

Any questions email or call. I will bring several transformers to the ETF convention. If you think you will buy one at the convention, please let me know so I bring enough.

We have designed a simple modulator to be used with British 405 line TV sets. It can also be used with Pre-1945 (AM sound) American sets. We ordered a number of printed circuit boards, and are making them available to anyone who needs one at my cost of $25 or 15 Pounds Sterling, including postage to the U.S. or Europe.

Pete has a Brand New 5AP4 in a sealed box from approx. 1940's and inquiring if any one is need of this CRT.  He has sold several of these tubes and all of the customers have been very happy with the brightness and clear focus of these 5AP4s.  They are an excellent replacement for the 5BP4 and are much brighter.  (201) 891-4899 or pdtrk120 at yahoo dot com  (*)
