Ok up for grabs are some Telefunken Amperex Mullard 12AX7 Tubes.

5- Telefunken ECC83/12AX7 long smooth plate tubes labeled The Fisher with the Diamond in the bottom of tubes. $40.00 each + shipping

3- Mullard ECC83/12AX7 tubes Labeled The Fisher all with Blackburn codes made in 1965 $40.00 each + shipping

1- Amperex ECC83/12AX7 tube Bugle Boy type with long plates and foil D getter made in 1957 $75.00 + shipping



These all have very nice printing on them and they have all tested good between 77% to 85% of new which means thousands of hours left on these tubes.

Well, I just pulled off the impossible by doing a double-blind comparison all by myself, purely by virtue of the fact that I completely and stupidly forgot what I did last. I guess that getting old does have its advantages after all :D

    Do you mean in an amp/ preamp for microphonics or on a tube tester? These were all tested on a Hickock TV7 tube tester and they ranged from 1900 Micromhos to 2100 Micromhos which is roughly 77% to 85% of new tubes. Considering that these tubes are known to run 10,000 hours plus some claim up to 30,000 hours there is virtually a lifetime of use left on these tubes.

    I have a couple of Fisher pieces that I can use these in. Nice coincidence they are labeled Fisher. I do have a few of these now. However, I am a tube **** and more is always better.!!

    Thanks for the speedy payment Carl. Test these to make certain they are as quoted and if for any reason you are unhappy with these tubes simply send them back and all costs including shipping both ways will be happily refunded.
