search : tube record player
From what I can see... there are old ads floating about, showing the ECR-1 and ECR-2 record players... dated 1957. That means, we are just about guaranteed no "solid state" parts, except maybe the rectifier... maybe.
This also could have weird... 35 / 35 / 12 / 12 / 12 / 6 configuration. That is the output tubes are 35v heaters, the preamp are 12v heaters, and the rectifier is 6v. The whole heater circuit is layed out in SERIES on 110v, and if one goes bad, they all turn off.... since they're in series. I tend to not think so though, as that was used mainly for lower ouput, lower cost table radios and such. This is a school room record player, and I recall them being plenty loud when ya cranked em up. Like, my old teacher saying "-CB- go tell Miss Scrivano in the next room to TURN IT DOWN!". I didn't mind, Scrivy had great gams, and nice jiggly assets as well.
I should add... the 45watts on the label are the power used, by the amp, by the motor for the record player, etc. The audio output is probably more like 5 watts of bliss.
