There is a metal plate going over both the volume and tone knobs inside over the inner plastic housing that prevents movement- held in place by 2 nuts, same as a house stereo. You can replace that stereo pot- check your local electronics store, the spacing on the pins may be different but you can jumper them with small wires just be sure the shaft length is the sameSuperduper said:Since the front row of pins of the repaired board can no longer be relied on to prevent movement, a new way to anchor the assembly needs to be constructed after the repair. Lots of hot glue, or some other creative method?
Like I said though. Most replacement stereo pots are going to be single shaft only though. So you might lost balance control. But who knows, maybe you'll get lucky. Who uses the balance control anyhow?stynger007 said:There is a metal plate going over both the volume and tone knobs inside over the inner plastic housing that prevents movement- held in place by 2 nuts, same as a house stereo.

And if not.... you might find that box is worth keeping as is... that looks like a little brother to the esteemed Sanyo M9990 & M9994! Might sound better than you think.reptoid said:

Cassette motor didn't work, and the sound was pretty bad.
Opened it, put some deoxit on the volume and tone pots, and on all the contacts I could find,
and now this thing works like a charm !... Even the cassette motor is back.
It sounds very good for such a small boombox.
One question for you: There is an "line in" input on the side, but no button to switch to this input (only radio, tape and "timer" to stop everything).
I can't get an external sound to come into this machine.
is it normal ?

basicly you have to put it in record but it might not sound , not sure if this box has the monitor function but more than likely it will record off the line in ,, so basicly you have to try it to see...and welcome to the site......
