FDP Forum / Amp Mods, Repairs, and Projects / Bendix 6384 Fender Showman Mod

So, I have a quad of Bendix 6384 tubes, and I was going through my tube stash because I'm going to be selling a large amount of them, and I did a little research and saw a video of an amp built around the 6384, and it sounded very good.

Then I saw on Tube Depot's website a converter to 6L6, now I know the screen voltage rating for those tubes is around 300V, so do those converters somehow handle that issue? I was considering modifying my '64 Showman head to take these tubes. Is this possible? If so what would need to be done?

Also if anyone knows the maximum heater current draw per tube for an AB763 circuit, that would be very helpful!

I don't know about the converters. For the heater current issue, with the 6384s in an AB763 circuit, you'll be increasing the current draw from about 2.7 A to 3.3 A, aprox 20% increase. That'll make the winding hotter, and the transformer hotter, but won't burn either out.
