This is the only reference I can find on this, having picked one up for $30, and building some small speakers for it. While the speakers need work, so does, I suspect, the amp.
Have not opened it up yet, as I was hoping someone already has. If not, we can use this one for everyone to play along.
The very first issue is the stinking tubes - they look like cheap 6n1, but not at all marked, having been over them a dozen times. The single tube is a EC2, which has a suggested replacement. Not real thrilled with chasing ecc83, but will if there isn't anything more enticing (6n23p, 6h30-dr, etc), but wonder also if the innards warrant butchery.
Some data here, but not what we need. Oh, and not using the dock at all.
