A while ago I ordered a few IV-27 tubes from an eBay seller, and today
they turned up. They were well packaged and all seem to have their
vacuum intact, though I haven't tried to test any yet.
They're not quite what I was expecting, though. All the photos and
drawings I've seen online show a tube that displays 13 decimal digits
and some symbols, like the one here:
https://tubes-store.com/product_info.php?products_id=646
My tubes have 14 full digits and no symbols, as in the attachment.
Is there anything particularly different about these? For instance, is
the pinout the same?
I hope I'll get a chance to try and power one up on the bench soon.
Fingers crossed they'll all work.
