Here are a few clips of a replica of mine, built with NOS resistors and caps and a set of marstran transformers :

Marstran transformers
Iskra & Piher carbon film and various carbon comp resistors
'mustard' caps
Erie preamp filter cap, bias caps & bright cap
PI filter is F&T
Mains and screens filter caps are RIFA
Alpha pots (modded to usual vintage values)

I modded channel II for less bass (1uF cathode cap & 3n3 coupling cap)

As you can see I added a PPIMV (this amp was my gig amp for years)

Nice wiring & sounds killer

Very nice build.

Cheers guys !

Great build as usual. I saw your West Coast build, I noticed that you used a 12AT7 instead of the 5687 described in the post. I was sceptical when I saw the valve amplification was only 16 to 18. A far cry from the 12AX7’s 100.
