Vintage Univox U-1086 head

There is an aux out and echo in, also there's a reverb adjust knob on the back.

The input is a four-input mixer that looks a lot like the Traynor YVM-1 that I worked on a number of years ago.  It had two separate jacks, a mixer output and a power amp input with the shorting terminals on the two jacks connected together.  If nothing was plugged into either jack, the four-channel mixer fed the amplifier.  The Traynor did not have any extras like reverb or tremolo.

I have a Univox transistor amp with both reverb and tremolo and haven't gotten rid of the hum or gotten the reverb to work, but it basically works.
