Should I update a vintage 16" broadcast transcription turntable?


I obtained a 16" Gray transcription turntable from the CBS Radio studio in Chicago some years ago.  It has 2 vintage tonearms that cannot accept modern cartridges without substantial modification.  It also has a massive motor, platter and spindle assembly.  It spins but I'm not sure about the accuracy of the speed.  I am debating whether it is worth the expense to modify this turntable to modern standards.  

I would need a new tonearm - not sure if a 16" or a 12" would be best.  I also am not sure whether the existing motor provides accurate speed control and likely would need to add that capability.

To do both would probably cost over $2K.  I currently have a Yamaha PX2 TT with a Hana Umami Blue cartridge.  I also have a Technics SP15, a Lenco L75 (needs restoration), a Transcriptors Skeleton (has a glass case), and a couple of Sony midfi tables.

I'm looking for input whether it would be worth pursuing the modification vs selling the table as is and buying a more modern TT.  I am satisfied with the Yamaha - it is very convenient - and want to either get the Gray to a functional state or sell it.

All opinions are welcome and thanks in advance.  I live near Atlanta and am open to a mod shop within driving distance.  The table would cost a substantial amount to ship.

On Lenco Heaven there are a few Threads about overhauling the Rek O Kut Transcription TT's.

The Grays Research Models seemingly share similar histories.

For somebody with A GL 75 or similar, Lenco Heaven will be of great interest.

Technics get a lot of coverage on DIY Audio, this might be a good pace to start  Post, I'm sure something will be on LH as well in other TT's.

You will only wind up with a rumble machine. Put it on display and buy yourself a good modern turntable.

For that price or not much more you can get an older Technics SP-10 with something like a SME 3012 tonearm (12") on a cheaper plinth and have much better performance. You only need a ~10" tonearm to play transcriptions, so you could even mod one of the Technics 1200 series to accept a longer arm, e.g. arm pod. Even one of those modern belt-drive Esoteric Sound Rek-O-Kut Rondine transcription tables, a bit "mid-fi", would probably be better than than dinosaur.

That motor there is SO noisy and RUMBLES too much.

You can re-purpose it for knife sharpener

😂 that is really funny. 

@ghdprentice I'm glad I could amuse you, but I was being serious and trying to save the OP from making an expensive mistake. I owned a rumble machine once and it was very frustrating, right up there with a noisy phono stage. When you have a very quiet record playing system you get to appreciate all the rumble and noise on the record:-)

Yeah, I understand. I think I ended up with something best described as rumble machine in my distant past. Not something you want to listen to.

Thanks, all, for your input.  I will heed the majority opinion and sell the table.  I think I'll work on the Lenco L75 and see if I can get that up and running.  I'll have to build or buy a plinth for it.  I have a Nottingham tonearm from an Innerspace table that was damaged during shipment that I can mount.  Think that would be a good match for the Lenco and the Hana Umami Blue cartidge?
