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

Duncan

Dunc, Darren lives 5 mins from me, so you should pop by for a listen :cool:

Thanks Marco for that endorsement and invitation.
I really need to protect what hearing I have left.:)


Darren wants to pick up the pre as he would like to hear my Quads driving the Kef105's.
He has a Quad 405 that needs TLC.

You're all ways welcome here.

HAHAHAAHA…. :lol:

Aye, you’re right enough!

When’s that happening then? If I’m free, I’ll tag along - in fact I could pick up Darren and we could both come together. Would make it easier for him, as I know exactly where you live :)

I'll second that ! Still using a Dunc DAC and ss power amp - just brilliant.
Oh .. And those Kef 105's are simply sublime/ transparent/ musical etc quite surprised how good a quad 405 can be. You are in for a treat.
