BK Video 5 to Class A amp

Anyone ever attempt to convert a BK video 5 to a Class A amp. It has 5 channels, with 2 output fet pairs per channel. I was thinking of combining the four channels into 2. Rated at 105 w/ch so looking at 25~30 Watts Class A? It has the Sonata front end. I can post the schematic here but was not sure if it is copyrighted?
