About This Listing

Selling a Lamb Laboratories PML 422 Vintage 4 Channel Quadrophonic Analog Discreet Mixer. Manufactured in the 1970's. I purchased this a few years ago with hopes of re-capping and cleaning it up, but haven't had the time. Originally, these were paired with a Revox tape deck for easy home recording. 

Currently, all the channels, eq and limiter on both channels work. Signal is able to be passed through all inputs and outputs. Many of the pots are scratchy and could use a good cleaning. A few of the potentiometers for fine tuning the input level are not working correctly. You can control the bigger 20 db steps just not the fine tune steps. I'd suggest replacing all of these for proper use. Meters currently are not functioning. They do light up. My guess is it's a quick fix. 

Item is all original and includes power supply. 

Please let me know if you have any questions. 
Due to the items age, I'm selling as is.
