MV1B no sound after stereo mod

[Misos]

I was moding this mv1b and didn't notice a blob of solder between the pins of the Power amp and powered it on.
It had no sound so I installed the stereo mod by Mkl.
Only after that that I noticed the blob of solder.
I replaced the OP amp and the yamaha 3016 but still no sound.
Does the stereo mod use any of the stock capacitors on the sound area of the board?
Because of the blob of solder i think it shorted the components on the sound area.

I would check what components were connected to that blob, follow the traces/connections. Probably fried more than one thing.
