Kind of like the old saying (from the "Pogo" comic strip): "We've met the enemy, at i ... kkissinger Wed, 18 Oct 2023 05:04:46 -0700 https://electro-music.com/forum/viewtopic.php?p=454327#454327 an OPA2134 is just fine.
what about opa2197? I checked the datasheet and the only concerning specification is the output impedance. can it be a replacement? Sohrab Sun, 03 Sep 2023 06:38:14 -0700 https://electro-music.com/forum/viewtopic.php?p=453801#453801 the issue was the store, where I bought the J112 had a datasheet with DGS pinout, but, the actual part I've got has a DSG pinout.

First time on this forum. I was sent over by Paul at soundtronics UK. I built the YuSynth EMS filter and had a similar problem to a user a few years back. Not sure whether this is even still monitored, but I need help if anyone is still out ... dummyplugconspiracy Thu, 23 Mar 2023 15:21:37 -0700 https://electro-music.com/forum/viewtopic.php?p=453396#453396 Did you rework the amp to be non inverting or just match Rene’s values? Benjamin AM Wed, 22 Feb 2023 06:36:24 -0700 https://electro-music.com/forum/viewtopic.php?p=452463#452463 Hello Volter,

Sir Yves states about the 78/7915 =" providing a reference voltage of +/-14.2V. This helps very much in increasing the stability of the VCO. "

at least your V++ looks like not meeting this values.

this is also affecting the 5V ( ... gabbagabi Wed, 31 Aug 2022 12:13:16 -0700 https://electro-music.com/forum/viewtopic.php?p=452258#452258 I have found an anomaly in the YuSynth Fixed Filter Bank design.

Yves' design is inspired by the Moog 914 filter, which is a half-octave filter bank starting from 125Hz in half-octave steps. Thus one of the Moog bandpass filters is labelled 700Hz ...

The difference between 101a and 101d is zero with no CV applied

With CV the difference will rise

Could be antiparallel LEDs + resistor between the two outputs a solution?
good thinking and worth trying. The for ...

If you want any help it is recommended to add a schematic to your post or at least a link. Grumble Fri, 11 Mar 2022 14:17:01 -0700 https://electro-music.com/forum/viewtopic.php?p=451401#451401 Hello

I'm going to make some of Yves's VCO's and having done this with TH VCO-1 from Mr Stites sites I thought I would do the same for the YS one.



This for the UV Film stuff. If anyone wants a 'how to' screencast I'll gladly do one.

Lowering the cap increased the ripple. The ripple is gone but as the frequency increases amplitude goes down. Not a perfect solution but acceptable.
