It is with great sadness I must report this amp has died! I can't believe it, I just purchased 2 Russian 6as7g tubes NOS from 1966 and was listening to one and the amp just died! I was very surprised as I've only owned it one month.
I loved the look, I loved the sound from the stock 6n5 power tube, I also purchased a RCA 6080 that sounded very detailed but I preferred the stock power tube. I bought a matched pair of Russian 6n3 drivers and also preferred the stock tubes. The Svetlana 6as7g power tube was sounding very good and then silence...
The amp seems completely dead. Oh well I tried Douk Audio. Too bad, just really to bad.
The month we shared was very enjoyable.
