Selling my Sonic Frontiers Power 1 amp, basically to thin things out and help fund other things. This amp has new KT-120s and National / Matshuista D7J8 bought from Uncle Kevin at Upscale Audio ….. still not fully broken in yet!! New tubes were $380.00 …….
I had a bad bias knob so shipped amp to Chris Johnson at Parts Connexion and had him replace all 4 bias adjustments. Also had it put to 4ohm operation while there. Chris said my tubes were on their last legs, hence my new tubes. I will include the used tubes.
Amp is in easy 8/10 condition and sounds beautiful. Chris shipped back with lots of extra foam, the Power 1 fits like a cocoon in a thick carton. Unit also has the tube cage not pictured. The KT-120 tubes turn this 55 watt amp into a 75 watt beast.
