Introduction: Convert Old Muzak Machine in to a Retro IPod Stereo
My friend has been carrying around this empty shell of a Micro Muzak Model 1008 for years with the intention of converting it in to something... someday. Apparently this was used in a university to pump the college station through all the buildings and had long since been left to fall in to ruins.
Using parts you can easily get and very little modifications to the actual case it came out looking preatty good. We reused the original knobs where they were still available for that original look. The tubes were left on the case to look cool, they do nothing.
I admit this is less of an instructable and more of a hey-check-this-out-able, but maybe it will inspire you to make something neat.
Step 1: Parts
- A cool old box for the stereo, in our case a Micro Muzak Model 1008
- Velleman k4003 30W stereo Kitt
- 12V Center Tap Transformer
- 2 RCA Jacks
- 1 10k ohm stereo knob.
- 1 On/Off SPST Switch
- 2 LEDs
- 2 LED holders.
- 2 1kohm Resistors
- Speaker terminal block
Step 2: The Case
Lets just admire tis case for a minute. It is definitely built to be uer serviceable, unfortunately too much of the amp was missing, but just check out the markings on the case.
Step 3: Clean Out
This thing had a huge transformer, tons of old hand soldered parts on the inside, it was missing a lot of switches and was pretty nasty on the inside. We cleaned it up and threw out some of the guts.
Check out the second pic on this step for a neat wiring diagram for the original amplifier.
Step 4: Donor
So I had made this ugly, yet quite functional stereo a few years back and it had served me well and sounded nice.
Now everything has been moved over to breath new life to the Muzak case.
Step 5: Insert
The existing holes in the case were perfect for putting in the RCA Jacks, switches and volume knob, we the extra knobs on for looks... Although the holes were all too big, so I used two washers (one on the inside, one on the outside) to make the parts all fit.
The rear of the case had a spot for hooking up speakers, although we drilled through that and used our own speaker jacks t modernize it a bit.
Our kit fit right inside the case with no problems, I just drilled some holes to mount the transformer and standoffs for the amp kit.
Step 6: Wire It Up
I wired the volume knob, on/off with and used an alloy RadioShack LED holder(#276-080)to keep with the look.
It worked out great, sounds good and looks cool too.
Thanks for looking.
