WTB Transistor array

I'm looking for an array of heavy NPN transistors to make a high current DC power supply test load.
Got a couple of Astron 50 amp units to repair, and my home made load tends to smoke when more than 20 amps are run through it.
If you have something sutable, shoot me an e mail.

I'm thinking...
Eight or more transistors in parallel
emitter resistors
all mounted to a stiff circuit board on a good sized heat sink.
Beauty is not a requirement.
It just has to run or can be made to run without a whole lot of trouble.
Thanks in advance
