Hi all,
I'm having a clear out again and found this valve pre amplifier I built awhile ago.
Nice SRPP configuration with excellent NOS 6n6p Russian military double triode valves plus a spare set.
Elevated regulated DC heaters and a pair of massive quality 660uf capacitors in the HT with Kiwami resistors.
Very quite in operation
24 Stepped Ladder Attenuator with metal film resistors.
Good solid case with room for a dac if that way inclined.
Single RCA phono input but you could easily add another.
£100 excluding P&P
