as m82 black box circa 1962

[James_Bond_007]

I am looking for a schematic for one of these. here is a link to an old advertisement for one..
Antenna Specialists M-82 Black Box

it is/was apparently a legal 4 Watt output tower mounted bi linear amp powered by phantom dc supply.

even better is if i could get my hands on one.

I could just imagine a stoner pro 40, some LMR-400 and a M-119 Super Scanner all reconditioned to like new.

this would be a bitching legal setup.

i always knew one of these had to exist somewhere.

yes i'm sure i want one for my collection would go good with my pristine CB-555 setup i have.

James,I had one of these light years ago,at the top of my tower with a hy gain super penetrator feeding it .
It's basically a receive preamp,much like a "bullet amplifier" for tv antennas. It made little if any difference on the transmitted signal,but made considerable difference on receive as long as you left your nb and anl off.
Eventually I took it down,but got a hair brain idea so I put it on my scanner antenna. It made a helluva difference from 30 to about 54mhz.!!
Something to think bout if you find one.
N9ZAS.
