Buchla 190 Dual Reverberator DIY Subject description: NOW CONFIRMED |

Main information page:
http://ebolatone.blogspot.com/2013/11/buchla-190-dual-reverberator-diy.html
This is an updated version, Feb. 21 2016. Working just fine with a clone transformer.
Edit 2018: Zthee/HumanComparator alerted me to an error in the layout. Have uploaded a corrected etch layout reflecting this change.
To mod an existing build, note that the left side of R5 should not go to the - side of C1; it should go to the Base of Q1. One cut, one jump per section.

I'm going to attempt an etch in a few days, if anyone who is capable of such might check the original schematics for errors and shout about such here...thank you for any assistance... _________________ We are selling emotions, there are no emotions in a grid. -mwagener

It's at synthfool.com. Thanks for asking/offering but:
I've been given photos of the parts side and trace side of an original module and only have one question about it, and I've sent that to one of the 190 owners who shared with me...will be updating the blog and doing a test etch likely this week although I'm still waiting on a few components. Will know a lot more within two weeks. Main issue: sourcing the obsolete Triad TY-30X transformers, two used per module.
Actually, I've been told the Gates I've drawn up from the 410 schematics don't work correctly. I'll likely be changing them over to original, all-discrete 110 Gates, and hopefully THAT schematic has no errors either! _________________ We are selling emotions, there are no emotions in a grid. -mwagener

This is now a confirmed working clone thanks to a modern audio transformer clone. _________________ We are selling emotions, there are no emotions in a grid. -mwagener

I'm rarely here, sorry for the late reply. Sowter created a clone of the original transformer and it works just great! _________________ We are selling emotions, there are no emotions in a grid. -mwagener
