BOSE wave/cd AWRC-1P w/DOM 020613
Early this morning ~0230hrs,
my wife woke me up and said the BOSE is dead. She wasn't
kidding...nothing worked. I figured the fuse blew. I know just enough
to usually get me in the ballpark. This morning, I opened the BOSE and
ckd the fuse -good, transformer primary input voltage -good, no
tell-tale burnt odor, primary windings on transformer - ~18ohms (note:
my meter is 25+yrs old and the decimal points are goofy so this could
be 180, 18 or 1.8...my best edumicated guess would be 18 ohms). The
secondary has about 8 wires output from the secondary (x2 purple, brn,
x2 blue, x2 blk, gray). Cking all the wires output - I get volt
readings all across the range, from 0 to 3vac to 60vac to 120vac. I
haven't tried resistance readings cause I don't know which wire goes to
what winding.
Transformer - BILLION #193372 rev.05 INPUT:120v/60hz R25-S3-0061 86R-142D-6 Made in China w/Date code 02/15
Since
the radio is totally dead....display, radio, CD...zero... and fuse and
trans primary input is good...I'm presuming it's the trans secondary. I
spent well over an hour trying to find info on this particular
transformer with no luck.
Anyone have anymore input on this...I sure would appreciate it.
If you can check ohms,you can also read volts. Open the radio again and look for DC volts on the rectifiers capacitors.They look like :cans", normally the color is blue. Check for positive dc v. against chassis ground. If no + tension,your rectifier or your secondary are open.

The Billion R25-S3-0061 transformer secondary output voltage as below:
Violet Brown Violet = 3VAC CT 3VAC
Black Black = 0 22VAC
Blue Gray Blue = 6VAC CT 6 VAC
Mine - just changed the input voltage from 110VAC to 220VAC (have to rewinding).
Hope help

SOURCE: transformer secondary out ???
please my name is dele i have this BOSE radio/cd system model number is AWRC2G which transformer burnt out rightly, that the input is 240volts which output is the problem and in nigria. please i just want to know the output on each coloured wire of the secondary that has 8 wires output from the secondary (2 purple - brn = volt, 2 blue = volts, and 2 black - gray = volts. so that similar that i can use to work it.
thank you

Oopppss...accidently double posted this. Might as well double post my solution.
Well...I've got it halfway fixed. Went into the cb and found an
oxidized area near the circuits controlling the CD player. Probably
caused from condensation of a drinking water glass I'm pretty sure.
Well, I cleaned the board up, fired her up and was fortunate to get
everything to work with the CD player being the only exception. Radio,
clock, alarms, aux input all work fine....I'm happy with that.
Thanks FixYa....other threads regarding the BOSE Wave steered me in the direction I needed to go. HOORAH !!!
Found the problem. Went into the cb and found a small srea the size of a nickel that appeared to be burnt up. Most likely from condensation off a water glass...no, I'm sure of it. Anyhow, it was in the area of the circuits that control the CD player. Cleaned the board and fired it up. Everything works except the CD player...figure that one out. Anyhow...it's the best I can do right now...I'm good with it.
