Assembled by Fab, the designer.
Mosfets 2SJ313/K2013
output Mosfets ALF16P16W/16N16W
Everything is matched.
£300 the pair + P&P. If I can find them I'll also throw in a new pair of 24v SMPS that can be used to testing.
Specifications of USSA-5 (obtained on 1 channel) (updated 2019-11-24)
Gain: 20dB (or x10)
Input sensitivity: 1.8 V-peak for output (20W rms)
Damping Factor (100 Hz , 8 Ohms): [35 – 45]
Output impedance: about 0.2 Ohm
Input Impedance: 22K Ohms
Max power into 8 Ohms before clipping: <25Wrms (at Supply voltage of +/-24Vdc, 1.2A Bias current)
Power in Class A (8 Ohms): depending of bias current
DC offset: trimmable to < 3mV
Rise time (10 to 90%) < 1.3us

Hi
Maybe provide a BOM to show how it’s worth.
I’m not sure but £300 ($400 usd) might be too high for 2 populated PCBs.
From the reviews I’ve read this is an amazing sounding amp.
Good luck with your sale

£300 is what I paid for them as they were pre-populated. Anyhow, open to offers and I’m including 2x 24v SMPS power supplies with them that can be used initially.
Can also throw in some panel mount RCA inputs for free, and I also have some brand new Jensen input transformers as well that I would sell alongside at a good price. A good way to have XLR input to a single ended amplifier.
