    Easy, I use these in my model trains to generate smoke!

    The windings are nichrome wire and there is a "wick" that goes around them. Capillary action draws the smoke fluid (similar to lamp oil) onto the windings were it burns and smokes.

    Alternatively, it could be the winding out of an L-pad.

    OK, how about the resistance element in a ceramic, non-inductive resistor used in a crossover. I've pulled them apart to make smoke units for the railroad.

    Cool

    Your getting real hot,I worked at a service center that did warranty work,in the repair pack we were told to add this part-this speaker company also had problems with other models-pictures to follow of the other fixes we installed and what I used them for.it was funny because they all had the same name,just different wattages

    Sounds like some kind of current limiter, resistance goes up when it gets too hot?

    I only use diesels on mine, I haven't seen any smoke unit for those...

    OK- all the guess were very good,when Bose first put out the model 101,people kept blowing the driver,so when they took it in under warranty,the repair pack came with a new speaker and what they called a "speaker limiter",the first 301/501's had the same problem-blown tweeters,so they would put a replacement tweeter,a fuse holder and speaker limiter in the repair pack,this one looked like a automotive light blub,if you have one of these models,take off the grill cover and look down the port,crank the volume up and you should see some light flashing.around my house when the kids were little I always owned vintage/highend equipment and had these things wired to my speakers,just in case the kids would play my sound system when I wasnt around,at first I had fuses wired in line but they blew to easy,these"speaker limiters"worked real good.I only have a few left,whats real funny is I made a call to "the mountain" a few years back and was told they had no idea of what I was talking about and if I had a problem with a product to take it to a repair center,I wish I had saved the flyier that came with the repair packs so I could have sent it to Bose,I may be older but I havent lost my mind. anyway they really did this kind of stuff to fix their BOSEjunk,I will post the picture of the light blub type when I dig it up.

    Yes, all of my diesels also have smoke units.
    Some even have multiple units.

    Oh yes, I do remember those limiters. When the 301s first came out, the tweeters were run quite hot and many dorm-room parties blew the tweeters. Installed many, many of them.

    JBLwoof, re: your experience with Bose today, I doubt there are many folks there who remember those days when you could actually meet Dr. Amar at the Mountain. The same thing happend at HP, where I recently retired - the smart ones left early....

    Cheers,

    David

    I have heard of this being done in electronic circuits also...

    the people were being purposefully vague, but they were alluding to having a small lightbulb somewhere in the circuit to help the mixer from being overdriven too hard....

    I know how you love Urei mixers so I have sent you a separate set of drawings with the Urei fix. Urei used the most advanced technology at the time that included IC chips. The problem with the chip is they do not have a high saturation point like the Bozaks transistors. By installing ... in the Urei circuit it acts like a variable saturation device. If you use a fixed resistor it limits the Urei from producing a higher gain output. The ... installed where I have shown you only absorbs the distortion and lets the mixer reach higher and cleaner output levels. This is a trick we used when we went from tubes to transistors back in the late 50s. Funny how ... installed properly can correct and make the Urei mixer respond and sound so much cleaner.
