rare 1960s Monarch Transistorized Stereo Microphone Mixer - Compact vintage rare mixer

super rare 1960s (!) transistorized!!! mixer.

meet the real revolution of the 60s, a small mixer with transistorized amplification!

gorgeous little thing.

it has had some maintance - the bottom is somewhat corroded, but it has a new battery connector installed, so the power itself is clean and safe, only the cosmetic surface had corrosion.

it also has a power socket installed, so it can work from 9v centre negative power.

for some reason - most of the 9v power adaptors that I've tried make the signal noisy, and they bleed into the audio path. it doesn't happens when used with the battery.

also the front switches have been replaced with brand new.

it's it okay working condition. everything works.

surprisingly it works even as a passive mixer, when no power is applied, but in this case the signals feature a lot of distortion.

quirky super vintage weird little thing.

sold with no returns at all.
