For sale is a modified/restored Harmon Kardon Citation II with 5687 triode front end, which opens up the sound from stock.

I've gone to HT, and just haven't use it like I thought I would.
Price is 1200.00, plus shipping. Will post additional pics of the inside. The work and parts alone were close to 700.00 Feel free to emaill with questions.
