If it has a 6BK4, it's a H12, which is doubtful!
IDK where they got that 6LE8 color demod circuit from. Many firms used it, not just Motorola.  |
Correct, the schematic shows no shunt regulator circuit, they seem to be going about it in an odd way, using pulses from a separate winding on the FBT via a diode and pot to try and tamp down the signal on the grid of the horizontal output, not very effective I would think, that diode will degrade over time being hit with those horizontal pulses.
