FS: Fully built and *tested* pair of AKSA/XRK ALPHA 20 Class A boards

For sale is a fully built, and tested pair of XRK/AKSA (Hugh Dean designed) ALPHA 20 Class A amplifier boards. ALPHA stands for AKSA Lender P-Mos Hybrid. Boards have been cleaned extensively for removal of all flux. A generic set of 10uf input capacitors are included for the owner to install if preferred. Input BJT’s are matched (for Hfe) for super low dc offset (<5mV). Output FETs are the very expensive IXYS types. This is yet again an excellent sounding circuit using Nelson Pass‘ Aleph CCS in the output stage, biased at 1.8A. Gain is set at 18dB. More info regarding the circuit is right here. Board is UMS compatible.

Price is $OLD/pair fully shipped in USA. International shipping is possible at extra cost. PayPal preferred.

Best,
Anand.
