Can anyone identify this Valve? [4212 or V1505]
I have a large valve, see photos.
The CD is for size The only marking on it is a hand written inscription saying CQ24 inside the valve |

Re: Can anyone identify this Valve?
Maybe a late version of the 4212 power triode (maybe -H with its direct internal connections, certainly later than -E), made by STC and others, based on the US-originated 212?
Look after it, it may be worth a pretty penny! Aha, found this; https://vintage-radio.net/forum/showthread.php?t=40716 |
