My Dynaco ST70 is oldest.
Bingo, James. I am using the same one matting with PAS-2. Both 50 years old, still kicking around like kids.
I super-restored both of them in my own most cost-effective way, WITHOUT need to purchase any new driver boards from vendors like most many upgrades out there. Now they both sing like a nightingale.
I'm a vinyl die-hard, my TT is also 40 years old vintage Thorens 125II. It plays my many hundreds of vinyls, recyled & brandnew like magic. I put it on my custom-built 100lb-heavy platform made of 2 hollow concrete blocks.
My loudspeakers are also vintage 40-year KEF 2-way bookshelvers mounted on steel stripods. I virutally rebuilt them to deliver superior sound from Pavarotti to Tom Jones.
Very old gears indeed. Yet the sound is not vintage at all - 3-D virtual soundstage, see-thru transparency, fast, dynamic & musical.
This old vintage system beats many modern tube gears, brandnames or home-brews.
