Who's run a Top Boost preamp thru the Express power section?

Basically a Rocket with a fixed bias EL34's. That might be cool.

There are lots of examples of that kind of amp build posted in the past.

Let me know if you need help finding the posts. I like Normster's Reverb Rocket with EL34's.

Cool. I have a little test amp with a TB preamp. I'll need to get out the test leads and try it out on the Express.

ac50s are sweet amps. I had to for service on my bench. the OTs are warm sounding, not much band-width really
