CV numbered diode - UK Vintage Radio Repair and Restoration Discussion Forum

music-centre · 6th Feb 2017, 6:47 pm

Hello All,
I was looking for a diode to replace a faulty metal rectifier in a small Radio Rentals radio and found a bag of NOS ones which are marked CV9935 - I did search for some info on it online but no luck.
I wondered if anyone had a book of the equivalent part numbers and could advise what sort of specification they have?
Thanks,
Steve.

Hi, Steve,

According to the CV Register, it's equivalent to the BY103.

Cheers,

Frank

Bit late to the party, but I found this on a google- perhaps of future use as it seems to contain quite a few cross refs

Hi,
Thanks for that, I also have some CV marked valves (somewhere!) so will have to mark them up, might actually use some after all the years I have had them.
