Two pairs of great tubes for sale:
1. Brimar 12AU7/ECC82, 50s, matched pair, bought as NOS, maybe around 200h played which is nothing for them. Old British Brimars are the best 12AU7s in the world (I’ve tried them all
). £200
2. Mullard EL37/CV586, 50s, matched pair, brown base, bought as NOS, run for around 300h. Not everybody knows that depending on the amp EL37s can be used instead of EL34/6CA7 but with much better sonic results. I’ve done it with Unison Research and Ampandsound. £250
