Subject description: 2 different comp-layouts
Reply with quote  Mark this post and the followings unread

I have just started populating the board for my ADSR module and notice that the JPEG and the PDF are slightly different.

I think R4 and R5 are wrong on the PDF (1k and 22k should be 100k and 1M..?)

The bit I'm unsure about is that the jumper next to R4 is missing on the JPEG version. Is that right?

Sorry I'm still perfecting my schematic reading skills! Wink

According with schematic and also with the component list I think that you are right and the correct values are R4 100k and R5 1M .

They were originally 1K and 22K but I changed this to 100K and 1M (see this thread from last december in this subforum: http://electro-music.com/forum/topic-30853.html

It looks as though I forgot to update the PDF file...

Nice one Yves.

I notice the jumper is missing in the new layout also. Is this intended?

The jumper is required I'll correct this.

I've finished today one Yusynth ADSR and its great Smile , It's very useful to have normal and inverted outs to control modules that don't have negative CV ( for example Yusynth EMS VCS filter )

Yes that was the point in including this negative out Wink
