adding a line input to a ghetto blaster

[Siamak SimKesh]

i hava a portable stereo that doesn't have "line in" jacks. Is there
anyway to add such jacks and how?

TIA

Try connecting your audio in to the high side of the volume control
potentiometer. If that sounds OK, put in jacks and a switch.

I once tapped into one at the inputs from the tape head to feed a
CD-player into it. (The tape transport was broke, and I hadn't used it
in ages anyway) Worked nicely after I dropped a couple attenuating
resistors into the mix so it wasn't over-driving the amp. Ran a set of
wires to the back, drilled a couple holes, and stuck a pair of RCA plugs
on it - plug in, set to tape, punch play, fire up the CD player, The
music goes 'round and 'round, and it comes out here.

It should be noted that that signal
will go thru a NAB de-emphisis network.
(equalization curve).

I didn't claim it was "hi-fi" - Just that it worked!

With the normal "audio hash" of the environment it was in, I doubt
anyone would ever know the difference anyway. It was "good enough for
the purpose", at the very least.

It's not like the speakers on a "Getto Blaster" are hi-fi anyway.. You'd
probably never know the difference on those cheap speakers they have in
them.

maybe... the easiest way would be one of those casette-shaped things people
used to use to connect cd players to car sterios.

otherwise you'd need to tap into the circuit near the mode selecttor switch
(if it has one)

I agree with the poster who suggested tapping the output from the volume
control. This part is easy to locate and solder wires to, and is (so far
as I know) always more or less at "line" level, being an interstage
control. That's where I would do it.

Not tape head surely as this would have special eq as with vinyl? Tape
deck perhaps?

Buy a panel mounting break jack type of the size you need.

Locate the volume control. Break the PCB track(s) that feeds the centre
pin(s) by cutting with a sharp knife and clean either side. Solder
suitable lengths of wire to either side of the break(s) If a stereo -
hence the (s) - switch on and identify left and right by touching the
input wire to the volume control - you'll get a buzz out of the
appropriate channel. Referring to the diagram of the jack socket, wire
each side to the break contacts. Connect ring to ground.

The three connections to a stereo jack are ring (ground) sleeve (right)
and tip (left).

But before find a suitable place to mount the socket on the case making
sure there is clearance behind. Keep it as far away from the mains
transformer as possible. You could use miniature co-ax for the connections
but in most cases ordinary wire will be just fine.

Try using one of those cassette tape adapters that are used for CD players
and iPods.

Or you can use a battery operated FM transmitter too.
