on pin 6. Pin 1, .006, pin4, 2.6vdc, pin5, 2.6vdc and pin7, 8.95 vdc. I
have checked all the electrolitic caps in the cir with my analyzer and all
check good. I have changed the vert IC twice the last time with a known
good LA7841. The B+ to pins 3 and 6 seems to high to me but with no prints
I am just guessing. Appreciate any help. Terry
