Does anyone know if the RCA 12BH7-A Data sheet is accurate for an RCA 12BH7? I have looked around and can only find the data sheet for the -A tube.

Hi,

Does anyone know if the RCA 12BH7-A Data sheet is accurate for an RCA 12BH7?

Yes.
The main difference, I believe, is the controlled heater warm-up time for the A version.

Cheers,
