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
