Model 510 15 tube version schematic

[Douglas Hankins]

Hello,

I recently acquired a model 510 that I am restoring. It appears to be a less common 15 tube version instead of the 14 tube. The schematics that are available are all for the 14 tube. Kent has suggested that this tube is a preamp for the phonograph. He is correct. That is what it is for.

I am asking to see if anyone here might have a copy of the original schematic from Scott for this variant of the 510.

Thanks for reading and for any help you may offer.

Doug
