Here's a few in my collection I might be willing to work a trade from.....
PPI O/S Amps
3) pcx-2125
1) pcx- 2200
2) pcx-4125
1) pcx-2400
1) A404W
1) A600.2 - needs repair
2) 2050M (1 is a am)
1) 2075AM
US Amps
1) USA 600X
1) USA 425
RF
2) 1000bd NIB
1) 1000bd - needs repair
How about a like new O/S PPI PCX-2400? Talk about BIG & IMPRESSIVE!! Not to mention, SQ and SPL, don't get much better....
Since you mentioned RF, I also have two NIB T10001bd's that can be strapped! (talking more than 5 bills for both though)
