M1194 PRODUCTION NOTES
1. Use three 8829 screws to align and attach the heatsinks to the board.
2. When assembling heatsinks to Q20(A&B),Q21(A&B),Q37,
ensure heatsinks are straight and sit flat against board. Add a very small
amount of RTV between heatsink and board if necessary. This prevents
the heatsink from shorting other components.
3. Add grease under middle tier mosfets.
4. No RTV under stones.
