troubleshoot VCO: no SAW, only SQUARE

[SubStyler]

check the area around C11, C31, C32 (voltages across) Q24, Q25 and the solder joints at S1.
maybe one of your eletcrolytic capacitors is bad or soldered in a wrong direction?
if you try to get saw wave, IC23 is getting hot?

cheers,

I triple checked and everything is soldered right. But I didn't solder C31 and C32 yet (the manual didn't say so), but that normally shouldn't have any effect on the saw right?

you're right. I did not know how far your build has gone at this time. I had the same problem recently and it was a faulty electrolytic cap... C11 to be exactly.
therefore my thought.

This is for reference to the future builders.

I had this problem too.

No saw, only square. R105 gave me a loud pop on the headphones.

After completing the VCF i could hear both waves.

so once again theres a vco completely build
but no saw just a square wave
all components triple checked...

...it doesnt feel right to just go on there must be a reason why it doesnt work
any suggestions ??? please!!

well, the square wave is made out of the sawtooth, which means it most likely works
i'd suggest continue forward and check the waveforms again later
