The output tube (6BF5) in my 75S-3B shorted out, I need to replace it. I have been checking some sources but cannot find it. I saw that it is similar to the 6AQ5, base connections are the same and the 6AQ5 can use higher plate and screen voltages. Can I replace the original 6BF5 with a 6AQ5? Any suggestions?
Thank you, 73,
