Hey all I have 2 set of tubes the first is a pair that was on my rouge preamp and they have a rogue markings on them and they are a pair of 12ax7 the marking for the these tubes is a bit fading out but the rouge stamp and the bird is there and I was able to make out the 12ax7 ...
the 2nd pair is mullards 12au7 made in great Britain .
Both set of these tubes are nice and well have not test but will work since i don't store crap ETC ..
here"s the deal I need some 6922 so anyone wants to trade let me know I can use a set of 2 but 4 would be better ... thanks
