12AX7 / ECC83 & 12AD7 vacuum tube valve job lot
Pair TungSol 12AX7 / ECC803S gold pin new issue. Less than 5 hours use - removed from a phonostage upon purchase for upgrades.
6 x TungSol 12AX7 new issue. All less than 5 hours use - removed when doing upgrades on new kit.
3 x no brand 12AX7 triple meca tubes. Origin unknown, likely Old Stock Golden Dragon (not the cheaper new issues). Looked ruggedised and similar in construction to the Russian 6922's. Seen some on eBay before at over £30 a tube. Hard to come - used with about 50 hours on them.
3 x NEC 12AD7 (two are matched). These are a substitute and are really really quiet. They were only made for 2 years in the 1950's specifically for recording equipment. Their price has risen a lot over the last few years if found. All tested strong when bought a few years ago but not used since purchase. These are the square 45 degree getter versions.
1 x Sylvania black plate 12AD7 - as above but the USA version (NEC version made in Japan). Square getter.
£130 all in posted U.K.
