Venerable Onix SP3. Beauty and beast of an amp.
I have replaced bypass caps w/ Sonicap Gen IIs and upgraded internal wiring for AUX input to
VHAudio OCC Teflon.
8/10 Light scratches on the Tranny covers (too light to show in pics but they are there)
Driver tubes are mostly stock, Power tubes are 6P3SE (amp also uses 5881/6l6).
$old.
