Late 50s / early 60s Rauland-Borg 4160B amp. Has four microphone inputs and two sets of RCA inputs. Taps for 8V, 16V, 25V, and 70V output as well as standard 1/4" speaker connections. Seems to be fully functional. I was able to test the RCA and microphone inputs, playing through some PA speakers and it works really well. I did remove the chassis from the case and spray each of the pots from the back with electrical contact cleaner before putting it all back together. This removed all noise when turning the knobs. One small lightbulb is burned out, but the other two are still good. The amp chassis has a slot for one (likely optional) vacuum tube, but I'm not sure what the purpose of it would have been (pre-amp of some sort?). The company Rauland-Borg is still in business. They began making audio products and eventually branched out into school and hospital communications which seems to be their main focus today. Underneath the rear lip of the chassis cover is an inscription which reads "Joseph Ward" so I assume that this was once used in chapel in the tiny town of Joseph, Utah. I also do have a pack of XLR gender reversal adapters for the microphone inputs.

I'm located in Cedar City and I cannot deliver to St. George or Northern Utah.
