5E3 Gain Boost

[leucein]

I built an amp based on a 5E3 circuit about a year ago. Built with only one input and beefed up the circuit to handle EL34's as well as 6L6's and 6V6's. Since I have half of my preamp triode available I would like to add a gain boost switch using this preamp stage, but am not sure how to go about it. If anyone could help me out with this I would be very grateful.
Also looking for a good 12 to go with this. Needs to be 8 ohms and needs to handle at least 30 watts. If anyone has aanything they might let go for a reasonable price I would be interested.

Hi

This might be what you're after - check out the 5E7 + mods page...

This is the circuit diagram...

I hasten to add that I have not done this myself, so I haven't a clue if it works or how it sounds.
