Very cool. I love the EF86 but there's only 1 brand the I use all the time. I have access to the E80F that was made by Phillips but haven't tried it yet. One thing I've learned is that pentodes have much less noise issues when they are run at low plate and screen voltages. My guitar amps typically have 100 volts on the plate and 90 volts on the screen grid. The huge gain that a pentode gives makes up for starving it for voltage.
 
I think I better gear up for some show and tell if I want to hang out here. Great work Mike.

I wish I lived close enough to either or both of you guys so that we could sit around a work bench and talk shop in the casual sort of manner that occurs when you are just passing time and having fun. I expect that I could learn a bunch from both of you.
 
Thank you for taking an interest in my project and making encouraging comments.
 
I enjoy getting chances to see examples of what you both do with your projects, and I hope you'll post some stuff as you get a chance.
