I have a Silvertone, Model 1591, catalog number 100-353 (Stewart-Warner?).
A cousin gave it to me at a family reunion this summer and asked if I could
get it to work. At this point in the job, the volumn control seems to be
shot; a victim of an overdose of mouse urine. Before I try to take it apart
and clean it would anyone have a working one of these in a junker?
If I can't make this one work and have to replace it with a stock control
would anyone know where the tap is set? Playthings of Past has some 1M
controls tapped at various points such as 250K and 500K. Since the tap goes
to ground through a capacitor, I suspect it may be a form of tone control.
If so, how critical would the tap be?

Harley,
the "King of Controls" here to help! I have any type you might need, any
taps, any switch, any value, most any shaft. Yes, the taps are for
"loudness" compensation. They give the control a "tone contour" to
counteract the non-linearity of human hearing.

Any set that used taps should have that type put back for best tone.

Yes, that is a S-W made radio.

as an aside, where does the spelling of Volume get to "volumn"? I get
that all the time here since I am a controls expert... I just wonder... is
it from "column"?

My IRC control book says this is a "special" control, "get it from Sears"...
hmm.... wonder why. IRC had tapped controls then... might be something
odd about how it mounts or the shaft?

Thanks for the reply, Mark. I'll get a picture of the volume control and
some measurements. Looks like I need to take the thing apart to see if I
can determine approximately where the tap is set.
The spelling of volume must have gotten changed somewhere between my
masters
degree and my 70th birthday. ;-) Thanks for catching the typo. I might
have gone another 70 years misspelling the word.

Just a though here,
Looks like the tap point is to decrease the volume or allow extra boost
after a certain point. Could that boost compensate for poor or normal tone
arm outputs?

Harley, send that whole control here. I can often replace the bad element
in that and reassemble it, so you dont have to make any shafts or anything.

Yes it is special, since the tone control fits over the shaft of the
volume
control and is held in place by clips that fit in grooves on the vc shaft.
If I can't find an exact replacement, what I do find will have to have a
shaft of the right length and be machined to hold the retaining clips.

I can put another tapped element in there, probably. I need to see what
type of control it is... who made it, so I can match that type of element.
Or, I could possibly make a whole new control from my stock. The stuff I
have was made up to about 1979... nobody else has all this stock as far as
I know. At the time that your control was made, the replacement lines had
not introduced the concentric shaft stuff.

OK, Mark, that sounds like the way to go. Can you reengineer/rebuild the
tap
also?
