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.
