Good news and bad news. I went back to the sale early this morning and got the preset selector. Thankfully, the guy running the sale saved it and set it aside. Bad news - we think that there is insufficient voltage on the plate(s) of the 6V6('s). They are running lukewarm with a filament, but that's all. I replaced the electrolytics, and that got rid of the 60 hz hum, but now there is just a small hum, but no audio. I didn't get a chance to check voltages this morning.
