Collins 356A-1 Tube Mic Preamplifier preamp microphone

Description

For sale is a single preamp from a Collins 212-G console. Unit is untested and sold without the 5879 tubes. I have no way of testing this. Sold as is for parts or repair only. No returns. All tube units like this should be tested and serviced before use Comes with manual and schematic I printed out from online. This could be perfectly working with new caps but I don’t know so that’s why marked as for parts or repair only. Will ship with great care. Thanks!
