Hi there forum. I just picked up a nice pair of Mark IV mono blocks. They are all original and have had no mods or repairs that I can see. They came with all the original Dynaco labeled tubes, original manuals, and they even had the original Dynaco boxes that they were shipped in - shipped to California from the factory in June 1960.
I want to do a mild restoration on them before I power them up. The transformers are actually pretty shiny looking and the chassis and cages look very good. The amps are pretty original so it's probably a good idea to keep them that way. I definitely don't want to experiment with changing boards or anything like that at this moment so I'm just looking at changing the critical components.
This would involve changing the quad cap, filter caps, sockets, board caps, selenium rectifier etc. I need a little help determining the correct value components to use. Does anyone offer a rebuild kit with caps and sockets?
What value of quad cap would you recommend for a stock Mark IV?
What value filter caps?
What value board caps?
Am I missing any other caps or significant components?
Any and all help would be greatly appreciated. I'd also like to post a few pictures as this project progresses.
thanks
