[rca2000]

So, I can shed a bit of light here.

Mine is a 7500W4, it is a 1964 model. It has a 25LC20QS chassis for the TV. It has the 8LT25 SS amp for the stereo. It has an 11L8T25 tuner. The TUNER is tubes...BUT the PREAMP--on the tuner is SS--under that shield. Plug-in transistors.

I drove a good way to get my set in 2003. The tube in mine, like yours--is quite good--but with BAD cataracts. The tv worked the last time I tried it. The stereo did NOT work right, when I got it. One of those caps on the amp at the rear--the coupling caps from the P-P outs to the speakers...was open. I change it out, with a 2200/35 and mounted it UNDER the chassis--to preserve the "look". I also changed one pair of the Germanium outs--from a similar amp I had.

Mine does work, but it has an intermittent power switch. I sometimes fire it up. It is in the basement here at the house, NOT in my storage garage.; Me and ONE other guy carried it out of the store I got it at. I DID have help loading it i my van--and down to the basement, but only ONE guy--and my hand truck too. Maybe my back was better then...

\My remote does not work right--it is that big chassis over the HV cage. Likely it needs a couple of caps--I will get to it "sometime".
