Matt,

Here are possible blown parts since they dont have protection:

Complete BFO & VFO, Q7, 8, 9, 10, 11

Mic amp Q12

If the PA was also connected to the same power then IRF510 final.

Check the Base - emmitter voltage of all transistors from Q7 - Q12

Before testing remove the VFO - Raduino signal from DDS1 jack
Short X5 to disable the oscillator
You will get wrong reading if these stages have RF running.

Good luck
