Restoring a RCA 21CT55

[etype2]

Walter,

You were right, it was the power switch that failed. We found out the switch was a replacement sometime in the set's history. It was incapable of handeliing the high current on power up. The switch had a 3 amp rating but the transformer was drawing higher current. Mike suggested we install a relay to draw the current and lessen the load on the switch which was replaced to the correct value. This was done to preserve the switch for long life. I'm so glad we did because the room light dims briefly on power up. The brightness control and volume control which were integrated with the power switch were retained.

The cabinet was in good shape. There was one scratch on the side which was touched up without refinishing the entire cabinet. The safety glass was removed and the CRT and glass were cleaned. I share your concern and the CRT was never removed during the restoration.

I need to refinish the brass around the safety glass. I don't want to remove the glass if possible. Do you know of a good product I can use to remove the patina? I tried Brasso and it had no effect.
