The hierarchy is allegedly as follows:

  1. Late 50's Foton "1540"
  2. 60's Foton 6P3S-E
  3. 70's & 80's Reflektor 6P3S-E
  4. 90's Reflektor Silver letter Sovtek 5881 rebrands
  5. Current black letter Sovtek 5881
I knabbed a NOS pair of the 1540's from Ukraine for my new Mofo #9. The thing is magic.

Anyone ever tried these 50's/60's early units? I've heard from a few sources that the 60's Foton are preferred in guitar amps. One enthusiast noticed "...more detailed attack with a sweeter decay."

NOS "1540" coming my way:

Figure they'll match the vibes of the late 50's Mullard long plates I love so much. Keep the Silver letter 5881's for a backup.

I get why Mark Cameron has to have 550v for the thing...that higher electrical "pressure" makes things more exciting. These "5881s" are just okay in most circuits, but man they open up with the higher plate voltage.

Anyways, anyone know about these commie war toys?
