After mucho thought I have decided to buy a pair of Croft 7 Monoblocks so my S4s needs to go (even I don't need both)
A bit of history.
I bought the S4s direct from Haden Boardman about 5 years ago.
Last year I took it over to Glenn who recapped and updated so as to run TungSol KT120's (changed the bias circuits and a few other bits and bobs including 1 of the bias external terminals)
It has performed flawlessly since day 1.
Valves as fitted:
Pair Telefunken EL519
Matched quad Svet 6550C's (sourced from Watford Valves last year)
Pair RCA 12BH7A black plates (NOS from Tube museum)
Pair Raytheon 12AT7's (NOS from AoS seller)
Pair GE 5 star 5751's (NOS from valve seller in HK)
Up until yesterday I was running the TungSol KT 120's - these have probably got about 200 hours. I had them Cryo treated by Frozen Solid (I have the certificate).
Having decided to sell the amp I thought I'd better test the Svets - perfect so have less than 10 hours on them.
I also have a spare pair of EL519's and various other tubes
Just to note I have removed the original plastic feet and support it on 4 chunky sorbothane blocks
The Svets bias at 70 Mv and the KT120's at 100Mv. They sound different (The KT120's more dynamic the Svets a bit warmer - horses for courses)
With all the above it's a bit difficult to put a realist price to sell but I reckon £650 sounds about right.
This is very heavy and I really wouldn't want to trust it to a courier so highly recommend collection in person from Riddlesden (West Yorkshire) - the buyer can then also hear it running.
