Cross brace in my LP12, bought as a complete LP12 in '85................
In reality my Grados RS-2s, 11 years.
Hey, I've had my current LP12 cross brace since 1983 so there That's probably my oldest owned piece of kit currently in use, no wait, it ties for oldest with my LP12 outer platter! As to oldest items in my kit, I think it could be the Mullard input tubes or Russian output tubes in the Stingray, or the Telefunken tubes in the Chinook. If we are talking whole items then the Naim Aro.
