Checking to see if there is any interest in this 01a preamplifier:
Made with boards designed by Radu Tarka
HV supply with CLC filter and regulated a la Salas
Filament bias with separate filament supplies, rod coleman boards and Mills cathode resistors
Gyrator and follower boards for low output impedance with FT-3 Teflon caps and Mundorf Silver/Gold/Oil output caps
Tubes are mounted on separate damped platforms
Stepped ladder attenuator for volume control
Included are 1x pair of 301a globe, 1x pair of 201a globe and 1x pair of 01a ST
I've always used it with one source and left the provision for 3 inputs total with a selector switch, if interested will wire it up.
PT can be used as 230V or 110V
SOLD

Those boards look to be missing some nuts and bolts. There was a diy dac sale on here not too long ago that "took a turn for the worse"
Best wishes with the sale 🙂

Boards are bolted in well 🙂. I did indeed see that thread, and it seems like a seller/buyer's worst nightmare...
