DMP3 is a transformerless inamp circuit, that could be done for $20 per channel + PSU, box, and PCBs. Easy to get eight channels of that in a 1u case. So yeah, two channels will cost you $150, but you could do eight for $300. Nothing wrong with an inamp circuit; they just don't have much of a "sound". So add the output transformers to a couple of channels with a variable output attenuator so you can smack 'em hard when you feel like it. That also eases up on the required number of rotary switch taps. Do a variable input impedance if you get bored--those features only cost a couple of dollars per channel.
