Default Leach 4.5 Trouble Shooting Help

I did a bone head move. After arranging some components in my Leach 4.5 I inadvertently touched the lead of the positive rail to the negative side of the power supply and POP. I replaced C21 (blew wide open), R32, D11, D12 and Q12 - 15. It still smokes the 100R test resistor jumped across the positive fuse clip.

Any thoughts would be appreciated. Perhaps its to far gone for a simple fix. Thanks.
