Hi all. Been a while since I've been around. I picked up another radio and got a non-worker. Maybe I should quit buying these things at yard sales. LOL.
I put it on the bench and fired it up. RX is good. Key the mic and found RX/TX light functioning. Look at the meter and I have no output. Checked audio chip and found it good. I went to the driver and found the legs on the chip were broken off and no longer connected. So I replaced driver AND final while I was at it. Still no power out. AM or SSB, no output. I don't see any bulging caps, flexed the board looking for any broken solder joints and had no change. IC4 has good voltage but its also switching the LED so I think it's ok.
Does anyone have an idea of where to check next? I spent 20 bucks on this one and it's not been hacked or modded. 1992 5pin Philippines model so I was hoping to have a nice little radio. Thanks for any help.
