Figured it out, the TLC555s should show some resistance between VDD and GND according to datasheet.
There is also a smaller resistance from the CONT to VDD terminal, in my case I measured it as ~70kOhm.
This means it is probably ok, no bridges etc.

Re: Extra9 - NAVA Expansion Kits
Hello,
About to begin soldering of the Extra9 PCB. Measuring ~128kOhm from +15V to Gnd which seems small. Is this normal?
The ICs are already mounted, don't see any obvious solder bridges. Also cleaned around the IC:s with isopropyl alcohol to remove any flux residue, resistance is the same 128k.
