Hi guys, finally building two of these. This is a tough build! A few questions so far.
Igor shipped R49 at 499K. The bom says R49 470K. Is this ok ?
Is 1N4002 ok for DP5, DP6, DP7, DP8 ? BOM says 1N4004 to 1N4007
Also how closely matched do the 20K resistors have to be on the quad 2181 vcas? The all measured 20.3K or so. One out of the bunch was 19.6k
