The Cabinet. (pictures) The cabinet is in mint condition.
The Chassis. Here are pictures and technical information. The chassis will be cleaned with water and a mild detergent using soft brushes to get into small places. Then, all paper capacitors will be replaced with modern ones (see the procedure for this). Each electrolytic capacitor will be tested for leakage and capacity. If bad, new electrolytics will be installed inside the old ones.
All high voltage (EHT) capacitors will be rebuilt.
