Does the trick for my Make Noise Bermuda VCO

My Bermuda only outputs Tri, Sine and Pulse, so I needed this module to get Saw. The sound is good but on my oscilloscope I noticed the amplitude of every other positive peak is only about 66% of the Ramp peak ahead of it. Could be my cheapo oscilloscope or I didn't nail the calibration. Again, to my ears, it sounds every bit of a saw wave so I haven't bothered to mess with it more. I suppose if I ever want to use it for modulation, that could be an issue....or a great new feature. :-D

I noticed a discrepancy between the FET specified in the BOM (2N5457) vs. what is in the Mouser shopping cart (PF5102). Specs between these 2 parts are quite far apart. Either that's a slip or the application is not critical? I actually used a 2N5458 in mine.

Response from PM Foundations | Jan. 7, 2019

Thank you Dan for your review. It does sound like a calibration issue (R26 Ramp Trimmer) but if you are happy with the sound then there is no reason to change it. It is still rich in harmonics like a saw wave. I have changed the Mouser cart from time to time due to the fluctuating price and availability of various FETs. In any event the most economical solution is the SMD part MMBF5457.
