This was a non working parts radio when I got it. It is now working but I am having a driver bias problem. It started out with a bad bias diode it swung my meter all the way over infact slammed it all the way over. I installed another MV1yH diode. Now I can only get about 8mA bias. it should be 50mA.
VR113 is good.
driver is good
final is good and new.
R158, R161 and R162 all good.
No glue on L124 and L134 and all parts in that area.
I did notice checking against a working radio. The single leg of VR113 where it gets it power on the radio where the bias can not be set VS. a working radio is .010 bad radio VS .001V on a working radio.
What parts am I missing? or any thoughts appreciated.
