looking for some matched quality ECC82's thanks
http://www.audiotubes.com/ BRENT JESSEE tubes has a good run down on what each sounds like and is cheaper than hotrox. There are lots of others but I couldn't say which is best.
Try Ebay look for mullards expect to pay around £20 a tube The two tubes on the left looking from front are the imput tubes and make the biggest difference They really do make a difference on the Eklipse pre amp regards
£55 for Mullard 83's ? they are thieves more like, I got 8 for £5 each at the Tonbridge Audio fair last year
Since you posted, I've had good service from http://www.eurotubes.com/ Eurotubes USA (JJ, NOS) however that was for JJ ECC82s and ECC83s not NOS
