Help to identify valves
Hi folks,
I have 4 valves that I'm struggling to identify. Does anyone have any suggestions as to what they might be? Thanks in advance! Oh, they were acquired in Australia in case that's relevant. Valve 1: The only code visible on valve 1 is 3C5/225 Last edited by DefiantSparrow; 11th Dec 2021 at 9:31 am. |

Re: Help to identify valves
Valve no.2 'YG' comes up as an ECF200?

Re: Help to identify valves
The B7G ones look like 6BE6 6BJ6? The PCF200 has a 10 pin base I believe. J.

Re: Help to identify valves
Valve 2 is ECF200, aka 6X9. YG is the Philips code for ECF200/6X9.

Re: Help to identify valves
I would hazard a guess that valve 3 is a 6AQ5, a baby brother of a 6v6.

Re: Help to identify valves
Valve 4 looks like it might be a diode pentode, directly heated. eg: DAF type or similar.

225 is a Brimar code for a 6BA6. " sensibly equivalent to an EF93" according to the Valve Museum. Regards, David |
