I modded my ST-410 Dyna a few years ago, following the manual for converting it to a monoblock, I used it to run my shop speakers that needed power, but imaging was not a primary concern.
I just acquired a second 410 and plan to monoblock it as well while I update the caps and other consumable components.
I mess with vintage Hifi and have several spare parts - HUGE heat sinks, transformers, etc. that I've acquired over the past 2 decades. My question here is can I update the output transistors of the stock 410 to a three-stage complementary Darlington output circuit? I found the schematic in an article of the Leach Amp - Output Stage (https://leachlegacy.ece.gatech.edu/lowtim/output.html) and Leonard Audio Institute - Output Stage (https://education.lenardaudio.com/en/12_amps_5.html).
Has anyone done this? If so, how and what were the results?
No, Dynacos are NOT a fire waiting to happen - as if this were valid given the number of them that are still out there, including mine, without incident.
No, I won't get another amp. I like experimenting, playing, and generally exploring my mind's ideas.
I'm not trying to be a negative Nancy, however, I've read every Dyaco 400 series posts here and many elsewhere and these 2 comments seem to be consistent, and usually from the usual suspects.
If anyone has thoughts, experience and/or expertise I would be in your debt.
Thank you.
