Please examine my Layout Rev A

Dan,

The 100k PI plate is on the 1st triode of the PI. The 110k is on the NFB side.

Scott:
I think that's what I got. 110/100 per your instruction.I've flipped the amp so that it's wizzywig with the open chassis looking out at you. I'm doing this one tubes up.

The current itteration is up top of the thread. If you aren't getting wore out give it another go. I've made it more readable with new value text.

Thanks
Dan

Anybody who might have had the misfortune of working off my layout should examine the switching. It was pretty badly hosed up I think. Using half of DPDT switches as tie points for grounds and whatnot. I think with the switch in the down position for deep, mid, and bright would have changed the scheme rather dramatically. I found this while wiring stuff.

Anyway, I've made some changes.

Swap the connections on the outside legs of the bass pot.

Thanks Heisthl, every time I look at the durn thing I find something else.

It's a wonder these things ever work.

Do you guys notice anything like, you know, unusual about the way my layout is wired? Hint: I worked it all out and then flipped it to make it easier to use when I had the chassis upside down. I am building a tubes up copy here. Hint: when you flip a photo, everything gets flipped. Hint: The pre tubes didn't light up. For some reason I wired the big tubes by instinct instead of reference to the layout. They lit fine.

I wasn't going to tell on me but there is the evidence out there isn't there. The brain trust never caught it and neither did I.

Good thing I got a whole roll of Kester 44



Hey Omar, after the laughter dies down lets just delete the thread.

Don't forget a roll of solder wick to get that old solder outta there too.
