I think I am pretty much finished for now. I did as suggested above to try and get the gain under control, worked like a champ. I changed the inter-triode...

I will try those suggestions and see what works best. Thanks again for the pointers Pete....

Again, thanks for the pointers. After having my wife threaten me with a frying pan last night, I decided that I really needed to get...

That last configuration has me almost there. I agree, I need to figure out some way to put a pot in front of the 2nd triode to tame it a bit. As it is,...

This is what I was thinking after the last comment -
I have already started working on this one. I am hoping with the 1M grid leak,...

Thanks for the input, I was planning on putting a grid stopper in series with the .022 coupling cap feeding the 2nd triode, that was my next...

5E5 Build - trying to add a cascaded gain channel
I recently completed an amp project designed around a 5E5 Pro schematic which turned out to sound very good. Since I only used one input, I decided to put...

Thanks for commenting with the advice on the resistors. I put a 1M resistor across the two contacts on both sides of the switch and...

Yes, agreed it probably came out of a tone cabinet, but it was definitely 6L6 powered. I ended up with the circuit above being modified slightly, primarily...

Those speakers look a lot like these Eminence 12774A's that I have which came out of a 90's era Fender Twin Super. These are heavy mothers, rated at 100W...

That is purely a perception thing. Depends on your circumstances. My wife considers the perfect bedroom amp to be the one that powers my Guild acoustic....

A couple more things -
The EZ81 is small full wave rectifier, this is what converts the AC coming from the Power Transformer to a pseudo DC...

Sounds like you have a 6AT6 Preamp feeding a 12AX7 gain stage which feeds the EL84 power section. Pretty much has to be a Single Ended design if there is...

Steve Morse used to play with Marshall's exclusively in the late 70's-80's. He added a Peavey 5150 in the 80's and would run them both simultaneously through...

Latest iteration based on jmaf's suggestion above. I hardwired the two grids of V1 in parallel and added a switch on both cathode bypass caps. I stuck with...

Alright, that should be easy enough. I will check it out to see how it works. Thanks for the input!...

Actually, I went to check that this morning and realized that I had originally tied a 1Mohm resistor between the switch/grid and ground as well, I had missed...

Bruce, I see what you are saying with that. Thanks for pointing that out. I will fix that as well. I guess I am surprised it has worked as long as I played...

For anyone still interested, I have completed 99% of the amplifier build. The chassis is extremely tight using 3-12AX7's, 2-6L6GC's and a 5U4GB Rectifier...

Good input...I was kind of debating on that, of course I don't have anything even close to 470 in a higher wattage resistor, which is way too typical. I...
