Info on 7922 valve
[ Nederlands Forum over Oude Radio´s ] Geschreven door Juan Carlos Gallego om 05. Dec 2000 20:56:03:
Please, I'm trying to find some info on the 7922 valve.
Production codes appear to be Philips/Miniwatt codes, but there's no company name on the valve, just a big 7922 on them, and the production codes near the base.They look like almost identical, and test ok, on my valve tester with 6922/ECC88 settings.
Could these 7922 valves be in fact, ECC808's ?
As I couldn't find any info in books or in the iternet, I have to ask.If possible, please answer to my email too, just in case I can't find this forum in the future.
Sincere thanks for your help.
