Hover mouse over pic and click the fourth button to enlarge.
It is too big for the scanner so I took a pic. It should be legible. Let me know if you need a scan.
The above is from my MM2 folder. The preamp schematic is the same as the one on Tisdale's site for MM3-4. http://www.verntisdale.com/AMIschem.htm
For some reason no one seems to host this 50 watt version online.

Rob-NYC:
I noticed a major error in that schematic you posted of the 50 watt amplifier. Take a look at the ac power cord and tell me what you see!

UGH!. That is even worse than the mistakes in the original print of the pre board. There were several solder points that were omitted. When I saw the original MM2 schem of the preamp I sat there for a while questioning whether I actually understood the circuit, or not.
Good amp build quality-lousy doc's.
It looks like they fixed them in the MM3-4 print.
BTW: For Eddie, the error is the dead short across the power plug.

Guys,
For some reason, Rowe, was famous for lousy, error filled, docs. Somewhere around here, I have the 17th printing of the WP-100 phono manual, that still has errors, in it-- ?? Ron Rich

Dang. No wonder it blew a fuse every time I plugged it in. Just kidding....
