Im stumped, what are these?
Well, you know what they say about a guy with a big wristwatch...





From what I read UA stuff was made for bargain stores. That said, the power transformer is pretty beefy, the outputs don't look bad, and the tube compliment was good as well. Wiring is very basic (scary really), no wonder the power cord and all the inputs were cut. Can't find the schematic anywhere...Ambassador consoles were sold at Maas Brothers department stores around here.
Not bad! At least it has a decent power transformer. You could have ended up with one of those line powered amps with two 50C5's and a 12AV6 + rectifier tube.

What thrift store?Picked up a pair of JBL 2115A full range drivers for $20 each yesterday.
Some of the speakers that get donated to thrifts are in pretty rough shape, but the woofers/mids/tweeters are still good.What thrift store?
Curious as to why they would just be selling drivers separately
Goodwill. They will put out anything they think they can make a buck on. Probably thought they were subwoofers. These were not drivers that were used in speakers. They were def professional tools. Probably someone's project they didn't want to throw out. The one cone was completely smashed and seized. Thankfully my speaker tech was able to get it moving again, and will give it a full recone.Some of the speakers that get donated to thrifts are in pretty rough shape, but the woofers/mids/tweeters are still good.
If one of the volunteers is into audio, they probably recognized the JBL brand & salvaged them. The store can still make a sale on something that otherwise would have gotten tossed in the dumpster. I've volunteered at a few thrifts & have done similar.
