Fisher X-101-B

Tubes Asylum

Questions about tubes and gear that glows. FAQ

I was never sure I have an X-101-B until I came across this ad. Part of the 'B' lettering on my unit is missing. Every other X-101-B I have ever seen looks the same as the cover pic on the service manual for s/n 70001 to 79999. Note that the knobs on my unit are different (no end caps to fall off), and I have 2 gizmos in the canter of the face instead of 3.
Is there something special about my unit? Maybe an early production revision? I can dig the unit out and check the s/n at some later date. The power supply transformer was shorted and about 15? years ago I found a company that had already done the engineering and had them make me a new one. I figured many or all of the transformers had failed.
Can anyone shed some light on what was going on?
Thanks,
Tom
