FS: John Wood Audio - KT88 Mono Blocks -100 wpc

Recommended Posts

I really thought these were keepers - my last ever buy but money is getting tight these days, and a newer car is needed.

These were custom built for me by John Wood, (John Wood Audio) as a mirror image pair.   They are in immaculate condition and come with Gold Lion reissue valves, an upgrade on the orginal fitment Sovtek KT88.  The only flaw is some discolouration to one of the input valve covers which I am sure John would swap out if asked. 

John gives a life time warranty on his amps and I can honestly say his after sales service has been exemplary.  He has never charged me labour for revalving, it has always been a while I wait service and he has always been most accomodating with times.

These are hand built (including the transformers) high end amps that will compete with the very best, which in my books makes them an absolute bargain.

Had several people asking for more information on John Wood Audio.   Surprised me really because I thought virtually all forum readers would have heard about John Wood Audio.

At a risk of sounding like  a fanboy I think I can honestly say that most people who have owned John Wood's amps reckon they are the best they have heard/owned.   They are hand built, including the transformers,  by John in Nottingham.  Build quality is exemplary although the looks might be a tad funactional.  You will note for example on the power amps how the transformers are set at 90 degrees to maximise performance.  What you cant see is the other 2 transformers inside each power amp and the super neat and tidy wiring. 

Power amps
Forum seaches,  Wam, Aos, PfM etc will bring up several rave reviews on the power amps.

Pre amp
John told me he developed the pre amps after the power amps when he couldnt find a pre that did justice to his power amps.   The early versions used valve recrifiers but John, as I believe Glenn Croft has too, later discovered that SS rectification worked better.

The pre amp on offer here is a later version with SS rectification,  it is low gain.  

The only thread I can find on the pre amp is at
