Question about Bose Wave Radio
I have an AWR1-1W that won't power up, makes a loud pop when unplugged. I know the fix for the newer version of this radio is the 5vdc power supply transistor. This is the older version with the 3 AA batteries for back up not the 9VDC battery. Do you have any suggestions. I can't even find the 5vdc supply in this radio, do you have a schematic. I have schematic for the series III of this radio but not the older version. If you can offer some info I'd appreciate it. Thanks
After some checking Q4 c3792 was shorted, Closest I had in stock was a nte85 that matched the specs. Radio works fine after replacing with nte85.

Kg4prc has the right solution. 2sc3792 bad (no display, popping sound when unplugged) replace with 2n2222 or eq. Pay attention to basing diag. Located next to bridge rectifier ( only TO92 pkg xistor on board) excellent!!!
