acoustic wave (aw1) problem

[gormak]

my acoustic wave radio/cassette (aw1, 800229) takes up to an hour to make sound when first turned on.

have stereo lock and tape turns immediately.

when it finally does start working it seems fine but if turned off momentarily
it takes several minutes to come on again.

a bad capacitor came to mind.

Bose has not responded to my request for information.

opened it up to find out i do not want to poke around without at least a
schematic.

sure would appreciate any advice/info (schematic)

thank you very much, gordon , gormak@live.com

Re: acoustic wave (aw1) problem

bose tends to be unfriendly towards DIYers and servicemen not "authorized," so if you can't find it in a google search, it is likely that the schematic is closed internally. Just post a picture and test the capacitors, replace 'em, and see what happens.

That would indicate that low power circuits are working normally.

a bad capacitor came to mind.

Those symptoms actually do NOT lead one to think of bad capacitors. Once the sound is present, is it distorted or good quality? If good quality, then poor solder connections would come to mind. Other troubleshooting steps might include checking line output (if available) for audio, and/or checking headphone output when the main audio is not working.

No surprise there. I'll bet you can fix this problem with a good pair of eyes and a dvm!
