Altec 1214a Portable Control Console, Mixer, PA Amplifier

Description

Excellent condition for its age. Fun little powered mixer. Would be great for a solo artist or small group. Incredibly quiet mixer stage. I wanted to use it as an outboard reverb unit for my DAW but the reverb preamp has some distortion issues. I would like to fix it, I think it just needs caps, but I have too many projects at the moment. I'm including a full set of original instructions and schematics.
The mixer channels have input transformers so the sound is really unique and smooth. The power amp is rated at 100W is not huge but good enough for small rooms, cafes etc.
From web research:
Neil Young noted that the mixers were used for the guitar P.A. on
Rust Never Sleeps.
I will double-carton the shipping box because of the weight. Will be well padded.
Works:
- Channels 1-5 work, both high impedance and mic level
- Power Amp works
- Ground lifter works and is a great feature I wish modern desks had
- Aux/Tape out work
- Accessory (mixer) out works fine
Issues:
- Channels 6 & 7 pass audio quietly
- Reverb/Echo preamp is distorted
- Could probably use a recapping to fix the reverb/echo issue, as you can hear the reverb in the mix
