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: https://tubeamparchive.com/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?
 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!

 Obviously there's more than one way to lay the components out. The proof is in the tone
