This Audio Valve RKV Mk II & Impedancer are in good cosmetic condition and excellent sonic condition. The RKV currently has Telefunken PCL805 tubes installed with the original Polamp tubes in boxes. I also have two sets of Mullard tubes and one set of RCA tubes I would like to include with the entire package. I also have an additional set of Telefunken tubes (some are diamond bottoms). One of the telefunkens is bad and caused a resistor to blow out in one channel which I have neatly replaced. Stronger resistors were supplied to me which I have not installed because the amp is working perfectly. These resistors will also be supplied. Hi-rez digital pics are available upon request. I would like $900 for everything but will entertain other offers if you don't want the impedancer or extra tubes.
