Just got a crusty old Dynaco ST-70 tube amp off e-bay to rebuild. It’s a project I’ve wanted to do for a long time. It’s amazing that you can still get replacement parts for something so old. The unit I got is in good shape electrically, but needs a new chassis. The chrome is old and pitted with rust here ans there. The output transformers also need a nice coat of paint too. Going to listen to it for awhile then do a transplant into a new chassis. It will. Give me the opertunity to replace older components while I’m in there.
I have been looking over the schematics and it’s a really simple design. Elegant simplicity that has stood the test of time. Will take some pictures when I get the chance. Plan on using it on my main workstation. Currently using an Emotiva integrated amp but I think it’s more interesting to use a preamp and amp here. Going to use a cheap Schitt amp for now and maybe get a vintage Dynaco pre-amp to rebuild later on down the road. I have also been eying a Dynaco Stereo 400’s on e-bay but that’s way down the road.
Want to get more into repairing old vintage equipment. Might hit some estate sales and garage sales this year and see what I can find… Not much in terms of deals in e-bay… Most people know what they have. Someday maybe a Sanusi AU X11! That’s a grail for me. Anyway that’s enough for now.
