Vintage Holmes Electric Spirit 4 1970's 400 Watt 4-Channel PA Powered Mixer
Vintage Holmes:
I bought this from a estate sale, it powers up no further testing.
I did turn all the knobs back and forth one by one and the all turn good so I would assume the pots are okay.
The front looks pretty good cosmetically, the rest of the unit is showing wear or either fading or needs deep cleaning. I did wipe down this unit and disinfect it.
I have nothing to test it with but it powering up is a good thing.
It is Vintage, It powers on & no electrical burn smells. I had it on for about an hour.
Selling as-is no returns.
Thank you.
