I've got a number of vintage pieces I use in various systems around the 'ole homestead.
I use the Pioneer SF850 (1976) as my active crossover in my main system

Also in the main system I use a pair of 15" Altec 416Z drivers as my woofers (early 60's)

I use the AR ES1 with a Grace 707 fitted with the Grace F9e (say 1982ish) with

...a pair of reboxed Klipsch Cornwalls (early 60's dating on the drivers). We call them the Cornzillas
I've got a vintage system setup in one of our our spare bedrooms. It's a Scott 299D, a Dual 1229 with a Sure V15 and a pair of Large Advents complete with zipcord and plastic interconnects.

I also use a pair of JBL 4410s (1983) in my wood shop

...and last but not least, my dedicated 78 system. The tweed amp is a Stromberg Carlson 420 (1952ish) which drives an Altec 824 Iconic (1954) and the table is a Dual 1019 (1965).
