voxpop Posted June 24, 2011 Share Posted June 24, 2011 (edited) Give your digital amp an upgrade to one of these great ECC83 / 12AX7 valves. All amps come with crap new type valve / tubes that sound rubbish compared with valves made in the past. I have a small selection of valves that would be an ideal replacement to modern valves. I have tested these and will offer a refund / return, excluding postage if you really dont like the improvement.
