Why not DIY amp

[Ian Mackenzie]

Its a good design but a bit dated.

Never built any but if you want brute power ..........

If anyone is looking for some extra Dynaco Stereo 120 stuff, I got a box full. No-charge.
A major problem I saw with the 120 was that the outputs fed through a big electrolytic capacitor-inductor assembly. One of these had failed on the amp I had. They probably didn't help the sound in the best of times.
I probably would have reused the transformer, but it doesn't have a center tap. Only a single supply rail.

Those are some nice tube amps. Where did you find the nice chrome chassis for your top picture?

They are not chrome, but polished aluminum that I picked up from International Audio Group. Horace is the same guy I got the polished transformer covers from.

Here is a shot of the inside of the custom 2A3 amp.

John W,

Have you had any takers on the Dynaco ST120 parts. I have two of these amps, which I have had to do extensive restoration on. After several replacement transistors and TWO output caps, I have two decent power amps. I also have a Hafler DH200, and two Dynaco MKIII monoblock amps.

Since I can't help myself in liking old Dynaco stuff, I would like these ST120 parts - especially the power transformer and the circuit boards. I will pay shipping costs, naturally.

Sure thing. Check for a private message.
I like the Dynaco stuff too. I have a couple MkIII amplifiers and just recently a very nice St70.

This looks like a very, very nice job. Very neat and orderly. This makes me want to do a DIY amp myself...something I have always had an interest in doing. I never got around to it, aside from building those Dynaco kits 30+ years ago.

Nice work!
