Dynaco ST-70 FS

I got this amp in on trade about a week ago.
It had a bad power transformer and had been tinkered with by someone who
shouldn't have

I
had a spare PA-060, so I swapped it out, put a new CE multicap in place,
changed it back to tube rectification, bought a new Sovtek GZ34, checked
all wiring, swapped out the domino caps for micas, and installed the
correct coupling caps using oramge drops. The original tube sockets need a
bit of retensioning, but I will leave that to whomever buys it.

I
have JJ KT77s in the amp, and the 7199s are the ones that were in the
board when I received it.

Complete with bottom, tube cage, and
tubes. Asking $500 shipped.

Additional
images can be made available.

Thanks!
