Fake GC10Bs - Actually GC10As

[Nicholas Stock]

Fellow lovers of all things neon...

I have a bunch of GC10As that are actually rebranded GC10Bs. They're still NOS and functional, but aren't infact GC10B's.... evidently this was a case of an unscrupulous individual or individuals back in the day with a load of GC10A's on their hands after the superior GC10B hit the market and deciding to 'rename' them. Anyway, I have some for sale at $15 each. Let me know if you're interested via private email.

Cheers,

Nick

This article from industrialalchemy.org might offer an explanation. They could be these “transitional” GC10Bs.

Yes, these tubes are what the Industrial Alchemy guys dubbed the 'transitional tube'. But that's not the case - it was just their speculation.

There seems to be a batch of these things floating around, though Nick may have fully cornered it now :). All are marked in the same way - note the absence of manufacturer name and date code. On a small minority of tubes from the batch it is possible to make out residues of previous standard Ericsson GC10A markings - another chap from here and I did a bit of work on that together some years back as we had both come across examples. Given that observation and that these things look and behave just like GC10As (same colour glow, same slow max speed etc), I think Occam's razor guides us strongly towards the tube washer rather than the novel tube...

Having said that, there was a developmental tube made en route to the definitive GC10B. But it wasn't marked like this and the glow colour is neon orange not purple/pink.
