Once Upon a time I cloned an Audio Research ref 5 preamp. We sort of. As a design experiment I duplicated the exact circuit but separated the audio section and power supply section into 2 boards and skipped the Digital volume control section. I used Genuine ARC parts except for the Tube sockets(I could not find an EagleCAD part for the Belton sockets) . Even the Special Moncrief output caps are Genuine ARC parts!
It was a fun experiment and it does work. just never got around to doing anything with it.
You will need to supply your own transformer, Rectifier, PSU Cap bank, 6H30's(5x) and a 6550 for the regulator circuit. as well as chassis, volume control, input's etc...but would also work as a buffer for a DAC etc.
Time to let some projects go.
Asking $100 plus shipping. The Output caps alone were over $50each new so! great bargain!
