I just bought a tall rack for my garage party system and it comes with a couple of TEAC PB32R units included.
Are RCA patch bays worth anything or should I just list them here as a Freebie?
I don't think I'll ever need anything like this for a simple party system and besides which I have no idea how they work
 
I have a Fostex RCA patch bay unit I bought used off of ebay for 30 bucks or so, lets me route some more rarely used sources into my preamp, and my record outs to cassette or one of several computer interfaces without digging around behind the rack. No issues after a year or two of use.
