Grado TLZ ???

I own a very old TLZ. It has a silvery body (probably aluminum) with a black stylus assembly. I am sure it is correct original, because I personally bought it new more than 2 decades ago. Rich, what is your question? I will try to help, but I am not sure I understand.

Yogiboy, thanks for the reply.
Lew, I am trying to figure out what I really purchased. My body is also silver. The box it came in is labeled Prestige Gold stereo pickup. The stylus on the cartridge is engraved TLZ v as is the replacement. I would like to know if all TLZ's are signature models or is the a non sig TLZ? Also what does the "v" designate? Thanks

I have been using Grado's for 30 years,so here's the scoop!
There was a signature 8 and 10 then they came out with the Z line which was the mcz,tlz,xlz,the v at the end of the number was the mark five version. If you have a gold with a tlz stylus something is rotten in Denmark!

yogiboy, I don't know that I truly have a gold. The box is marked gold, the cartridge itself is marked Grado on the mounting surface, JG on the silver portion of the body and on the front it is marked jg with Grado below it. The cartridge came with the tlz v stylus and a spare. I am just doing my homework. It was not represented in a deceptive manner. I suppose when I mount it and listen I will learn more. Thanks for your input and anything else you could share would be appreciated.
Thanks
Rich

Very simple. You have a Grado "Gold" with a stylus assembly that has been upgraded to that of a "TLZ v"; they are interchangeable. My guess is that performance-wise, you are not quite at the overall level of excellence of a full-fledged TLZ, but fairly close. Output of a Gold is 5mv, output of a TLZ was (if I recall correctly) 1.5mv. Output is determined by the body that you have, so yours outputs 5mv. The TLZ retailed for $500 when new.
