[Amps] Refurbishing a Henry 3K Classic II

[Manuel R. Alonso / KC4MNE]

Hello,

I am not an expert, but I would just fire it up. The Henry's have oil filled
capacitors so you should not have any capacitor failure. I am also pretty
sure that it has a trip circuit on the b+ line that will trip in case of a
B+ short. Henry mede very nice amplifiers that were built like a tank.

Subject: [Amps] Refurbishing a Henry 3K Classic II


I have a Henry 3K Classic II that hasn't been turned on in over ten years. I
am hoping to get it on the air again. Any input or ideas on the following
questions would be most welcome:

1. What type of cleaner and lube is best for the chain drives?
2. Should I attempt to clean and/or lube the variable inductor? It moves
very freely and looks clean, but I am a bit concerned about oxidation or
tarnish.
3. Do the contacts that engage the fixed tune caps ever need burnishing?
3. Should I let the tube "cook" for a while before applying B+? If so, for
how long? It is a 3CX1200.

Anything I should look for specifically? Haven't worked on a Henry before.
Seems like a pretty nice amp.

Thanks in advance for any suggestions.

73,
Theo K4MO
