Tube Audio Design TAD-60 Tube Amplifier

Mullard Reissue EL-34 tubes installed. Hand adjustable bias pots - the more desirable ones.
Haven't used it in many years except to test it out here and there. Still works and sounds great.
Only blemish is that one of the banana posts that hold down the cage needs to be replaced if you want all four working. Three is more than enough.
