I’ve enjoyed previous circuits by Bajaman and, needing an ABY box, I thought I’d give this one a try. As usual the layout has yet to be verified. Let me know if you do.
Update (03.12.2011): I built this the other day and experienced some problems. I’m looking into it now. Probably a good idea not to build this right now.
Update (04.12.2011): Fixed. There was a small mistake on the schematic and I had to rework a good part of the vero layout to solve this. Built this last night and this is now verified.
Update (24.01.2012): I actually finished this a few days ago and I’m very happy both with how it works and also how it came out in the end.
It does not have ground isolation, so probably not.
Hi, can I use this to use two amps at the same time without any ground noise problems?
BP = bipolar, or non-polar if you like. It’s either a regular capacitor (those are all bipolar) or a special kind of electrolytic that can be oriented either way. A regular capacitor in this size will undoubtedly be physically large. A bipolar electrolytic can physically be really small , but retains the less desirable characteristics of electrolytes; poor tolerance and a short life span.
Another noob question from me… What is “BP” for the capacitor ?
