This discussion became a bit much for the other thread so let's bring it here;
The first image is obviously your damaged board. Notice the part circled in red. The second is @xrror's P5KPro. Notice the part circled in red.
The 2 circled parts do not match and after looking them up, they are slightly different. Unfortunately, there are a crap-ton of parts out there with both the "A00A" and "A009" designation. However some digging revealed information.
Both the "A00A" and the "A009" are low frequency amp 15v(max) parts. However, the A00A has a higher line trigger voltage threshold, which likely affects the signal output for the device. What this means is that while attaching a 42t might not cause damage(very unlikely), sound output will be affected and will likely be a bit muffled, if there is output at all. Granted, this conclusion is based on research done without the schematics for either board so I could be wrong.
Either way I am confident you will not do any more damage by trying a 42t, regardless of whether it works.
Not so fast @Robert B . There is one part that throws that conclusion into question. Let's look at both photo's.@xrror Thanks a lot for the time you took to help me! Indeed that transistor is 42t - I'll have to remove the 1p/A1p. Good thing that I didn't power up the board yet.
