MCM has some in stock, though their shipping for small orders is kinda a ripoff: http://www.mcmelectronics.com/product/TDA7240A . It's also not clear whether it's the vertical or horizontal one (TDA7240AV or TDA7240AH), though I believe you could make either one work with a little bit of creativity.
I have a few junk MK boards. Some of the MK have the sound on board but I dont think it was until MK3 and up. I will check to see if I have one I can pull.

I believe the one he's referring to is a KI 1 or 2... I assume this is the one he brought it to the arcade repair party, which had a chunk blown out of the amp. It was certainly KI board style.
