Question about Bose Wave Radio

3 Answers

Bose AWR1-1W older version, not Series III, no power, pop when unplugged.

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

    I have the same problem - no power, but a pop when unplugged. I have no technical skill and would not like to try repairing it myself, but Bose wants $99.00 plus shipping to fix it for me. How much should I really have to pay?

I've got a simillar problem... will be looking into it this weekend. U402 is supposed to be the 5Volt regulator.
The input to U402 is U401 its a 12Volt regulator.
You should check both...

    R406 (1 Ohm) acts as a fuse for the the input of U402, replaced R406, now the display works and the unit powers up.

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!!!

When I went to turn the radio on it made a loud squealing noise that will not stop


My radio stopped working and I took it back to the Bose store and they gave me a good credit on a new one. You should give that a try.

Is there anyway to fix a blown Bose Speaker (201)?


The only 2 solutions are: 1. Just find an equivalent driver to replace. Re-wire new driver speakers into the enclosures. The old 201s may have had decent drivers (although probably paper cone) for back then, but now just about anything will sound as good in those particular cabinets.
2. Call Bose and exchange them for current 201 speakers (higher clarity more powerful). Bose will give you about 30-40% off I believe on a series 5 model. They now pay for inbound and outbound shipping as well.

Bose wave radio won't turn on


Unfortunately Bose will not release their schematics or parts lists, effectively giving them a monpoly on repair of these units. Their web site, www.bose.com, offers to repair most Wave radios for $100 or to provide a $200 allowance towards purchase of a new Wave. Before you spend the big bucks on theis trouble-prone product though, you might want to check out the new HD radios -- better sound and MUCH lower prices than Bose.

Bose wave radio wont turn on


I have one that is doing the same thing. Will your radio make a POP sound when you unplug it? I was told by Bose Tech it is 15 yrs old and they will not work on it. He told me that if it makes a POP sound that it is not the fuse or power supply???

Replace fuse Bose Wave Radio


For the AWR1-1W turn it over and there are 4 screws that you must remove. When your looking at the circuit board the fuse is just below the power supply and back of radio. If the radio makes a ‘POP’ sound when you unplug it may not be the fuse as power is getting past the fuse. I have the same trouble with mine. I called BOSE Tech and he said if it makes that ‘POP’ sound after unplugging it is not fuse or power supply. They will not even allow me to send it in for repairs as the radio is over 15 years old and considered unserviceable.

Maybe someone else can give us a quick fix.

No power up


Considering that power is present, popping sound is caused by a faulty Q401, 5V supply for display.

Good Luck.
