so the diodes protect the output driver chip from overvoltage/dc/+48 'backfeed' on the line output of the dualcomp...one could forego the $16+ in capacitors and put in $1 worth of diodes in the varimutand in the dualcomp there are no coupling caps feeding the grids and no diodes--another $16+ saved by jumpering_am I missing something? is there a high pass designed into the earlier iteration that is not warranted with the diode-string preceding the varimu stage? or has it been determined that the coupling caps are not necessary?
