I have a Kyocera R451 rcvr I'm looking at and the VCC on all the chips (not the power amp but all the "low level stuff")....seems awfully high.
Like 17 volts (?!)
This is an early 80's rcvr...hard to find any data but I did see one of the chips datasheet (LA1245) that shows an absolute maximum of 17 with a typical VCC of 12v.
How many times have you repair guys seen chips sitting at higher voltages like this?
The things working alright but it has some "issues".
