“Elements” - 12AX7 SRPP preamp with remote

 












Built mainly from parts on hand including tubes (Gold Lion), enclosures, output caps and power tranni. The power tranni I got free because the filament windings were open. I had a 12V tranni on hand and was used here for heater voltage. 

Three inputs and Alps remote volume control with RFI/EMI filter in the external PS. Russian military metal clad output caps in a Hammond extruded anodised Al enclosure with a big gold knob make this a smart looking build. Brilliant sounding as well as smart looking, a great use for so many parts which had remained unused.
