Hi All, did anybody notice the radio on Pawn Stars the other night. It was on right after the Gemeni Space Jet Pack when Chum-Lee was making his comercial. They showed it for maybe a couple seconds when he was asking a girl some questions. It is a Grebe Synchrophase at least that is what is on the dial scale, no model number anywhere. They sold that radio for just under $1000.00 dollars in non-working order. Well I have it on my bench to restore and I have burned up the Internet trying to find the model number with no luck. If anybody recongized it and knows the model number please let me know. I'm hoping to start on it tomorrow night. Thanks A Million, George T

There were a couple of iterations of the Synchrophase, but none worth anywhere near $1000. They are battery-powered TRF sets with a typical 5-tube layout. But instead of three tuning knobs, the three tuners are ganged together with chains to achieve single-knob tuning. Mine is a good player.

For info, try right here on this forum: http://www.nostalgiaair.org/Resources/001/T0000001.htm

But, simple TRFs barely need a schematic. Their wiring is essentially their own schematic.

Hi Doug, This one is a circa 1934 Tombstone with 4 knobs and a urn cut out. I haven't pulled the 6 tubes yet to see what they used. Best 2 U, George T

That doesn't sound like a Grebe Synchrophase. Fotos would help. Post them on a freebie image hosting site, and post the link here.

Hi Doug, will see if I can post a couple photos, been quite a while since I've done it. George T

See if it is on this website:

Hi Terry I tried that one, I spent hours looking for it with no luck. It is a 1934 Tombstone and says Grebe Synchrophase on the dial scale. Thank You, George T

The better-known Grebe Synchrophase was a battery-operated TRF set from the mid-1920s. However, Grebe made the transition to superheterodyne sets in the early 30s and also adopted the term "Grebe Synchrophase" as the radio brand name. So, there were several models of "Grebe Synchrophase" in the early 1930s - six tube, eight tube, and so on- all were different, all were superhet, and each had its own model number- but with the same brand name,"Grebe Synchrophase". Confusing, but presumably done for the purpose of cashing in on the name recognition/goodwill that the TRF Synchrophase generated some years earlier.

Hi CV, I believe this one was built just before they closed down. I probably don't need a schematic it looks like somebody rebuilt the electronics in 1983. At least that is what they said on the back of the chassis. I put some pictures of it in Photo Bucket but am stuck there and having trouble posting them to this site. This radio is kinda like a model 89 on the Radio Attic site it might be a model 83 will find out when I see what tubes are used. Best 2 U, George T

George

Compare it with schematics here:

http://www.nostalgiaair.org/Resources/001/T0000001.htm

I have MU1, MU2, 6 and 7 Syncrophase. None of these would be considered tombstone. HS models are superhet.

"Confusing, but presumably done for the purpose of cashing in on the name recognition/goodwill that the TRF Synchrophase generated some years earlier."

Makes sense. Grebe did a lot of print advertising of their TRF sets, using a caricature-like spokesman, an Asian coolie named "Dr. Mu" (racially insensitive by today's standards). (Mu is the Greek letter used for vacuum tube gain, get it?) The Grebe TRFs had model numbers MU-1 and MU-2, etc. They had a distinctive and attractive cabinet design, a good circuit, and were among the first TRFs that controlled the three-stage RF tuning with a single knob.

Hi tried to post picture from Photobuck but couldn't copy and paste URL. Must be doing something wrong. Properties comes up and when I click on it the URL comes up but won't copy. George T

Thank You Richard, I was about ready to pull what little hair I have left out trying to get a picture on this site. Best 2 U, George T

George, will you take $100 for it? Just kidding.
Good luck with the restoration. Has it been varathaned or is that just the flash?

PS I have that same Heathkit SG-8. Which makes a decent AM transmitter, BTW, although a little underpowered.

Hi John K
That's what I offered Pawn Stars for that radio a year ago. They wouldn't buge from the $999.00 price tag. The radio was restored in 1983 so it does look pretty good with a good shine. But the top is cracked and warpped.
That is a good transmitter for the money and works good enough for the old radios. One of these days I'm going to replace the caps in it and it needs a little cleaning but it works pretty good. Best 2 U, George T
