More Class-A than ever!
So I recently bought two NAD's, one of them has a problem with no FM the other has a completely dead tuner. This one seems to have an issue with no FM, the FM muting works until you try tuning when it just seems to stop working and all the tuner picks up is static, AM seems to work.
I've measured some voltages found some missing or wrong values. IC403 is missing voltages on pins 17 and 18. IC 401 is missing voltage on pin 4. IC 404 has 7v on pin 17 4.5v, on pins 18 and 19, pin 20 has 5v and pin 21 has 1.7v, I also noticed that Between TP 7 and TP4 is 31.5v which I believe is supposed to be 3v - 3.1v.
I've also checked my antenna is working and gets a very strong signal on my SX-737. Any help would be definitely be appreciated!
