I have a B&K 700 that probably needs to be re-tubed.

I can identify one of the unit's two tubes as a 5Z3 rectifier, but I can't ID the second tube (lettering has rubbed off.)

Does anyone know what this second tube is?

Thanks for any help.

It should use a 83 rectifier and a 6BN8. You can find a manual on Bama.
