Vintage (early 1970s) 3M Mincom tape machine preamp for the model M64 (could be used with the M23 if you can live without a VU meter, or otherwise obtain one). The last picture shows the 3M tape machine these amps were originally installed in.
Excellent condition. Brand new electrolytic cap, I was going to use this for a project that never materialized.
Great spare for the 3M Mincom collector/owner. Or, repurpose the massive input and output transformers to use for a DIY project (mic pre, line amp, etc.).
$100 or best offer.
Shipping will be $25 to the U.S. 50.
