What's the oldest piece of gear in your system?


This site is here for the buying and selling of Audio equipment. This causes me to wonder if most of us have relatively new equipment. If most of it is new, what is the oldest piece of equipment still in use, and why are you still using it?

My oldest piece is a Sota Star Sapphire, but it has been upgraded. It was originally purchased as a Sapphire in the 80's, but was upgraded to a Star Sapphire about two or three years ago.

What's your story?

A Conrad Johnson PV-5 preamp. It's a 1984 which i bought unopened from a dealer in 1986. Since then it's had new higher grade caps, new power supply, and obviously many different tubes. I love it and probably wont sell it but I am looking into a new preamp, possibly Shindo Monbrison, Audio Horizons TP 2.1, or DeHavilland Ultra Verve.--Mrmitch
A mid 70's Technics SL-1300 automatic turntable. I am just to lazy. I also have an early 1980's Technics SL-10 Linear Tracking Automatic turntable with Technics 310 MC cartridge. A truly unique device.
Tho I don't use them at present, a first generation Koetsu and a battery powered, perhaps the grandaddy of battery powered phono step up devices, Marcof PPA-1.
