MAT 03, Q81 - Heat sensitive?

I have a question regarding these components. I recently built an EN
Option 3 VCO. I first used 3906s for the PNPs and a regular carbon
resistor for the CV converter circuit. After I tested everything and
made sure all was working, I replaced the PNPs with a MAT03 matched pair
and the resistor with a tempco. Once I did this the cv input of the VCO
no longer worked.
Could it be that I damaged either of the components because I didn't use
a heatsink? I can't figure out why the circuit stopped working. (BTW, I
did check the pinout of the MAT03).
