Califone 1440/1410 50L6 SE build w/series filaments

[tnmgcarbide]

here's a schematic for this amp i found from an old project . this is the only copy i've ever seen - it was inside the record player's filthy case.
a very simple build . the stock version was frequency limited , and i recall tweaking some caps to open it up a bit . i didn't add the proper isolation
trans, but i would highly recommend it .
