Got a good buy on this radio (or so I thought). I knew the final had a bad rep, and sure enough, I received the radio, and no tx. Pulled the final, and it tested bad.
I sourced two replacements, threw one in, and I had tx. 3 swingin to around 6 on a.m. everything seemed fine. Flipped to lsb, keyed the mic, and got alot of static through the talkback on the ext.speaker. Gave it a aauuudddio and poof...nothin. Back to no tx.
Pulled the final, and it tested good. For the hell of it, I tried the other final, and still nothin.
My next thought was to check the driver.. but I dont know where it is lol.
Also, the side of the chassis, where the audio chip, and Im guessing the a.m. regulator? and voltage regulator? Gets very very warm, just sittin at idle in rx.
I cant find a schematic for this radio, so im guessin its still a big secret. But if anyone can point me in the right direction as to the location of the driver, or add any extra insight to this issue, I'd much appreciate it.
