Actually the problem was caused by a bad 470uf cap, that was used to filter the powersupply for all the analog amps. Replaced the cap the unit works like new.

This is caused by a faulty filter on the IC allowing main frequency effects to go to the speaker, not a user servicable repair, it needs to go back to the shop.

Bose radio bad hum


one of the most common sources of hum is a failing power supply.
I don't know your radio specifics..... however, some things to consider/try : if it can be battery powered, try it with batteries.
If hum disappears, then source is power supply. Power supply
hums are usually 60 or 120 Hertz (cycles per second). The most
common failure component in power supply, causing a hum, are
the filter capacitors. If you do try to replace these, be very careful
and discharge the old caps before you remove them - to avoid a
(potentially dangerous) shock... caps can retain a charge for many
days, sometimes. Another source of hum is if the radio is close to
a flourescent light, or other appliance which may radiate power. If so,
try moving radio. If the hum is high pitched, then more info is needed.
Hope this helps!

The display is suddenly filled with information (sometimes unreadable). Everything has now stopped working.


From the sounds of it the microprocessor is scrambled, this can be caused by a power surge or thunderstorm, unplug unit, press and hold power button for 60 seconds in an attempt to clear the processor, if this fails this will be a job for a Bose factory trained technician.

The Wave Radio uses the AC power cord as an antenna. Perhaps the two outlets are wired differently regarding ground and hot.

My 10+ year old Bose wave radio/alarm on fritz


Replace the 3 AA batteries that maintain memory & backup alarm function. That just may do the trick.

Has a fairly loud (annoying!) hum. Changed


there is a short in the speaker wires somewhere inside, which is not as bad as it sounds since a qualified or experienced person can just take off the case and make sure there's no wires touching and get them out of each others way.

The other cause can be electrical cross interference in your homes wiring. I like to think it's the first thing... Hope it works out, awesome radio- have a nice day!

My Bose wave radio with aux. for attaching to a CD player stopped working. I tried plugging it different places. It is an old system.


Unfortunately Bose will not release their schematics or parts lists, effectively giving them a monopoly on repairs. According to their web site, www.bose.com, they will repair most Wave radios for $100 or give you $200 credit towards the purchase of a new set. Check your options before you spend the big bucks though. A new HD radio, with better sound and a MUCH lower price, might be a better choice than repair of a problem prone Bose.

JCR-160 clock radio Clock running slow


The clock works off the frequency (hertz). In US the electrical wave frequency is 60HZ/sec and in India and many other countries 50HZ/sec. Hence, the clock slows down about 6 seconds or so every minute.
