In Reply to: Dynaco ST-70: upgrading using mod kits or replacing existing parts? posted by newbie on July 24, 2002 at 10:26:20:
I love this kit and think the price is silly-cheap: It keeps the things you liked about the ST70 and fixes the not-so-nice parts. Sonically, it's lively and engaging and has no particular vices. This is complete rebuild, not a modification, and it does away with the exposed circuit board, so you can safely operate the amp without the cage. The hard-to-get 7199 tubes are also eliminated. I was happy enough with the sonics of a borrowed Welborne ST70 that I thought "I could stop right here". But the amp was only a loaner and I didn't have an ST70 of my own. So I bought a pair of Ron W.'s Laurel IIX SET amps instead and couldn't be happier: Though mine are the base models, I've felt zero need to change out any of the stock parts (Ron's idea of stock parts includes Elna Cerafines and Hovland Musicaps); I just like firing them up and listening to music. Sonically, the Laurels make happy sounds like the rebuilt ST70, only more so.
