100 watt 70's sorta....

A little off the reservation on this one. It really sounds great though. Really big cleans, and loud, and the gain range is very nice and useful.

VERY cool, i`ve done a 80`s 4 x 6V6 dumble and bogner circuit on a Marshall chassis, gotta LOVE the real estate! Nice job!

Here`s a pic of that 80`s thang!

That looks really great!! I've built a couple 4X6V6 this past year for the first time. Ran them at 470v b+ and they came out sounding pretty cool. The Marshall chassis gives you lots of opportunity. Geographically I'll change a few things in the next one most likely as things got a little congested around the inputs on this one.

Beautiful job! Puts my work to shame.
Just had mine out of the box.
I had a external OD trigger pot in but decided to return it back to the layout with the 1.2M/220K/500pF/33K network.
Fired it up, sounded like crap, V2 voltage all over the place.
Turned out I forgot to ground the junction of the 220K/500pF/33K.
Sounds VERY sweet now

What PT do you use for the 4 6v amps?

Is there any reason why the screen resistors are flipped? Better heat release?

The build looks great!!

I used a PT that was similar to the old New Sensor Marshall 100 watt PT but had it built with a 6v tap for the relays.
