In Reply to: Transmitter Tube SET. What Are Your Overall Experiences? posted by Mister Pig on September 5, 2021 at 08:28:26:
MP,
First paralleling DHT are not good. What happens is when you have a transient one of the tubes will pretty much shut down the other unless you directly couple the driver stage to the grids. Then the whole heater thing is a mess.
You can make a good sounding 845 amp that will pack close to 20W at 900V. But make sure you use big iron.
Stay away from 805's and the other transmitters they all pretty much suck.
You can make a pretty good sounding 6550/KT88 SE amp to 20W pretty easily. I made a bunch of directly connected driver stages that got A & A2 power to 20W+ in some of the guitar amps I built.
Thanks,
Gordon
