Oldest gear still for sale is . . .

My first amplifier was the Dynaco ST70 Stereo Tube Amplifier with Cage.  I am guessing its age around 1955 but I really do not remember.   

This thread is about gear that is still in production. Why are all of you listing gear that hasn’t been produced in years? Reread the post!

You are correct yogiboy, I got "still for sale" mixed up with "production."

That’s right gentlemen. We’re not talking T-Rex or Sabre Tooth Tiger here. They stopped making those models a long time ago. What we’re looking for is a Crocodile - was here, way back when they were making the T-Rex, and still in production today.
Racking my brain to come up with the oldest, yet current, audiophile component I’ll throw out the SME, S shaped, tonearm. (I consider it to be a component, rather than just a part).
I know when I put together my turntable-base-tonearm-cartridge system in 1980, the SME had been around for a few years already - a little longer than the Shure V cartridge, if my memory serves me well.  The tonearm has seen a little improving over the years but no radical change from the early 1970s.
I’ll say that’s my Crocodile.

I wish we could say the Shure V series. They should never have stopped making it, even if they had to change the cantilever. 

Does anyone know when Jelco started selling the SA-250ST? It had to be in the 1980's, right?
