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

Looks real good! A possible suggestion- make the valves do something by wiring the valve heaters into the PSU so they glow when turned on. If the current is too high or wasteful, put some red LEDs under the valves to cast a red glow into them.

Can I possibly get the instructable/plans for that older stereo? Thinking of using the Velleman K4003 for some creatively housed ipod amps, and would like to see clear instructions on wiring the power source and volume control. Also thinking of going with a standard 1/8" female input instead of an RCA jack... Thanks!

I added this to the Vacuum Tube group--although I see now the tubes are just "for show..."

(you can remove it if you like...I guess I can add a group, but not remove one.)

_{(Actually, I did remove it--as the administrator of the Vacuum Tube group...)}

Anyway, good job on the project...

Hey Gmoon- Thanks anyhow. Hey do you know of a good tube kit to start out with? I have been looking at this one: http://www.tubesandmore.com/scripts/foxweb.dll/moreinfo@d:/dfs/elevclients/cemirror/ELEVATOR.FXP?item=K-502

Thanks,

I like tubesandmore, they're a good outfit. I'm not familiar with the amp, and my personal interests lean more toward guitar amps rather than very linear, low-distortion stereo amps. But a google of the tubes (11BM8) brings up comments about the kit:

(links to other threads are buried in this one. The opinions all look positive...)

Honestly, you can spend an obscene amount on a tube stereo amp (and much of it would be wasted, IMHO.) This one appears to be good, AND you can still tweak it in the future (upgrade caps, output transformers, etc.), if so inclined... Pretty tough to beat that price, too.

I still like mine, 8 watts of brute force power :), but it is all hand made. I would say go with the one from AES, it seems to be a good little amp and for the price you can't beat it.

[gmoon]

Yeah, there's aways the DIY approach--if you're brave... (@Joe--didn't throw out that transformer, did ya? They are the most expensive components of a tube amp, anymore.)

Sweet Instructable. If I somehow get a Muzak Machine thing, maybe at a yardsale or something, I definitely want to do this. Awesome Instructable! +1 rating.

Nice! You might want to add something to the power cord to prevent it from getting torn out

Actually I have a "knob" of electrical tape on their, good call! -Joe

Cool! Nice Instructable!!!
