Aleph p1.7 completed board for sale.
Solid brass bar keeps all mosfets equally hot, relays are itt, gain fets are harris devices, attenuator section uses sfernice resistors and some nos siemens 0.1% resistors. In/out capacitors are roederstein mkc, capacitance is smaller than advices 10uf, but if load is not tough its alright.
Ps photos are from construction, bad soldering on adc chip is corrected.
Asking 230 euro.
Board size 20x30 cm
