Re: Old valves worth collecting ?

They original, real deals, are far more rugged and resilient than commonly imagined, and as you suggest, I doubt that any recent start-up can ever replicate the qualities of the mass manufactured ones that many of us revere.

Re: Old valves worth collecting ?
They look like a couple of old 'pulls' to me, value zero unless tested.
The EF86 is in the wrong box, possibly because the valve from that box is now in the thing that EF86 you have was taken out of because it didn't work properly. Those rarely wear out but they do get hummy and noisy. The EC92 has some of its pins bent together, that's a thing that some engineers do to show that a valve has something wrong with it. Bending the pins in stops it being idly tried again in something else, causing confusion in a later repair. |
