ADM preamp and line amp cards
18-668 cards
23-666 cards

All cards have new electrolytic capacitors. 8 - 668 cards pass signal and the THD measures in spec. 3 - 668 cards pass signal, but are out of spec. 7 - 668 cards don’t pass signal, but have all new electrolytic capacitors. (3 of these are missing input transformers).

6 - 666 cards pass signal and the THD measures in spec. 6 - 666 cards pass signal, but are out of spec. 11 - 666 cards don’t pass signal, but have all new electrolytic capacitors.

These sound great! Well designed discrete circuits.

These are also listed on reverb
