Hi Mike.
Finally getting time to work on this again.

On your last note where you wrote "bad 807" were you refering to R807, H807 or C807?

There are 4 wires on the J808 contact. I removed them all and E/B voltages on H806 are 16V/15V.

Here's what I checked/replaced.

H807 Zener diode replaced
H806 transistor replaced
R805 checked OK
R807 checked OK
C809 Replaced in recap

C807 is a ceramic cap .04 uf. Can I replace it with a film cap? They list C806 as a .047 film and C807 as .04 ceramic. Why did they use a ceramic cap here?

Thank you Mike!
