Hello i ended up with a set of eico hf-30 's. These were badly cared for and i got them with broke tubes rust ont the transformers and correded sockets. After cleaning up replacing bad / missing tubes and soldering on a missed connection for a cap i got htem working. The sound great.
I want to make them like new. I plan on;
Repainting the transformars black
Replacing all the tube sockets with ceramic ones
Replacing the cap's with the kit that is avalible. (some are physically deterating.
Now here is the big questions.
I have 2 powercors I snagged off of copiers and was planning on using these to replacing the old lamp cord ones. The new ones have a ground wire should i hook this up to something?
These were originally designed to be turned on by a preamp, currently out of lazyness i have them both plugged into my preamp directly and the preamp plug was previously modified to just be on allways. would it be an advantage to plug the supply directly into the wall and use a set of industrial relays? I would power these by the preamp switched power. These look almost like tubes.
Thanks FortyTwo
I can post pics if you would like

Hi fortytwo,
Nice score! I would use the same type of tube sockets that came with them. Ceramic will look weird and you can get some ceramic that are really poor quality.
The "new" power cords you have now are way too heavy. Thinner ones are fairly cheap. You would ground the chassis (green wire). Remove the little cap to the AC supply.
I would tend to turn my equipment off when not in use. That goes for preamps too. A power bar is a low tech way to do this. Relays would be fine. Whatever is safe and floats your boat.
Enjoy the amps!

thanks
The cords i have are 14gauge wire but i also have some with thinner isulation but i beleive both are 14 guage. A good supply i found of cheap power cords are pc cords just cut the plug off.
I know i have corrosion in my sockets would it be better to clean them rather than replace them? and how?

Hi fortytwo,
Thinner power cords would make your life easier. Seek them out.
Order new sockets, just not ceramic unless you buy good ones. Take the time to measure resistors. You can solder the new parts (resistors and caps) to the new sockets before you stick them in. It may be easier. Antique Radio and others have a good selection of tube sockets. The original brown or black ones would be in keeping with the factory supplied hardware.
