need recommendation for power amp

[elic]

Hi,
I need recommendation for a decent class AB amplifier kit (preferably from ebay, but any online store will do). My constraints are:
+38V -38V power supply (200VA transformer). I am going to use it for connecting musical instruments: guitar, bass, organ.

thanks!

to be clear: when I say class AB I mean not class D. Bipolar or mosfet output will do.
