Reworked the Express layout and...
came up with this. Used the A1a schem and made it to fit in a Marshall cab. Sounds kick ass and is more quiet than a couple previous builds I made. Very sensitive to crappy preamp tubes!

That's an interesting layout. Nice clean build too!
I have done something in that direction with my amp but I kept the filter caps grouped: http://ampgarage.com/forum/viewtopic.ph ... highlight=
I had first planned to distribute the filtering but my board became too long. Using smaller caps and a cap can seems to be the solution.
I see that you went with separate bias pot adjust; cool!

Re: Reworked the Express layout and...
Ah, very nice! I noticed you didn't bother with twisting the filament wires either. I haven't heard a noise increase so I'll be doing this in the future.
Re: Reworked the Express layout and...
ahhh yes.... a very nice and tidy build!

Looks Sweet
Dynaman What Electo caps did you use and values. (For power/plates pre)
Nice and tidy (wouldn't mind trying to duplicate your build) if you don't mind.
have you a layout that you could share ?
Is that A 50watt marshall style chassie ?
I'm new to this but like the looks of your build so neat.

Top drawer execution Dynaman! I get the feeling you thought about every nuance to your brilliant layout. Perhaps more than twice.
You maybe moonlight at NASA's thermionic division?
Please tell us whose resistors you chose. {I'd try those in my Komet's power supply} Are they flame-proof metal oxide or something more esoteric? That 9K1 halfway down the epoxy board, appears to have vents on the end.
How does she sound?
Now I'm thinking I goof off a little too much. {I need to focus on getting some building chops like yours}

Dynaman, this creation of yours is so muff huckin' punishing that I have to go to bed without supper!
