    Ready for some fun

    Folks, I need some suggestions for Dynaco ST projects. Here's the deal:
    I just got an old ST-70 that needs a complete refurbishing. The chassis looks OK (not great); I've yet to test the transformers though I don't have any reason to think they're bad. It has the older, more marginal power transformer.
    I'm also bartering with a friend for ANOTHER ST-70. I'm sure I'll get it eventually, but I don't know its condition.
    What I have on hand are tons of tubes from guitar amps and so forth...EL34's, 6L6's, 6p3s-e's, and a bunch of KT88's. All kinds of signal tubes. I also have two Hammond 1650N output transformers (60 watt 4300ohm).
    Should I use those transformers on one refurbish as an ST-120 type amp, or are they not up to Dynaco quality?
    I'm replacing a Dynaco Stereo 400, which I built in 1976! Also a PAT-5, built the same time (it's not working well any more).
    I've got "upstairs" and a "downstairs" stereo setups, both with Klipsch KLF-30's.
    How about some ideas? Thanks!
