Hi All,
I rebuilt my MK III's pretty much by the Dyanaco Manual. I kept everything pretty much stock with the exception of replacing the quad cap with a STS board and a Dynakit Dual Bias upgrade.

I have run them for about a year now and have no issues. There is no hums and they run cool. The schematic makes sense, but I didn't know if I could keep my dual bias circuit and if the STS board would play well with the mod. Here is what I have so far:
