Lep pozdrav za MIK-a i Vinka!

As I promised, here are files of my protection system. It would have to be divided into several posts because of pixel and KB limits (max. 100KB & 1000x1000pixels) for uploads on this forum. First one is the schematic.

I must say I am impressed , I am using snips from your designs in my "mongrel" amps (your cap multiplier) and am pleased at their flawless operation. I recently fried :hot::hot: one of the amps with screwdrivers and aluminum filings ... thought I took out the speaker but lucked out.

I normally don't use the designs of others , but your "omni" seems to be perfect. I am using 78-0-78Vdc rails with a standard EF2 output stage. Has this been tested ? And do you have layout ?

Thanks... good doctor , very concise .. especially the explanation ... as usual. 🙂

The whole thing is 198K/bytes below for others. I will give credit to you for this "gem". It is on the mongrel website as well.


BTW - you would not mind if I made a few "BORA voltage boards" to round out my mongrel collection. I would like to hear them myself. What voltage stages would you recommend for standard type 2EF's ??
