So does mine! To me (having both at one time and running out of room), it was a pretty easy decision to keep the older 4 knob version and turn loose of the later version (pencil box) that had a weak (going gassy) metal CRT.

Wow, i should never have clicked that link.

The 4 knob version, with the voltage doubler, has the cascode tuner, 6BQ7A/6X8 and the 41MHZ IF.
RCA was an early player, with the 41MHZ IF. :thmbsp:

To paraphrase a comment on another discussion:

Maybe if a couple of us TV collectors found an early Gibson-Les Paul guitar and drilled holes all over it for sorting out our capacitors (stand their leads in the holes), or strung up a bunch of Telefunken 12AX7s as Christmas-tree lights (run them at 8 or 9 volts, nice and bright!), when the audiophools came crying, we could explain how this type of junk is to us.

Now there's a cool idea! :scratch2: I didn't know tubes could glow bright at such low voltages.

On a similar note, I junked a Dual turntable for its motor. I'm sure the audiophools would have wanted it for nothing because a little bit of rubbing alcohol got on the platter and ate away a little bit of the rubber. Aside from that, it was too complex for me to want to bother fixing, strobe lights are almost impossible to find and they're not a bolt-in swap for most other turntables of the time. Give me a much-simpler Garrard any day for the rare occasion I do play records.

Wow religious intercourse Batman that guy must really be on some good meds... I like the fact that he shows the cap and component board looks like it was soldered by a 5 year old. I think we should all sit back and see if he actually pulls this off if he does, I guarantee you my old TV collection will literally be worth millions... Needless to say I'll have a lot of CRT's for sale as well as chassis :-)

Maybe it was. Brian's 8 year old daughter has demonstrated superior soldering skills.

Thats 1 of the idiot sheeple of today who think TODAYS GARBAGE is so good and they dont give a crap about the PURITY of the past!!!

Well, he put over $2,500 worth of parts and labor into it, so OF COURSE it's worth that much! Now pay up. ;-)

That's about as bad as the guy who cuts speakers into suitcases and asks absurd money (and occasionally gets it!):

Oh--That's just plain Wrong on all sorts of levels, not least the god-awful build-quality.....
