I think I will try a baffle in this amp to keep the PA heat away from the
PREA and interboard headers etc . Those ribbons were surprisingly hot from
that high power test. Obviously if on repeating that high power test , the
PS h/s climbs excessively then my thinking is suspect and can easily revert
to as "designed". Incidently this amp , no load, SMPS runs at 380KHz , much
like the other Mark Bass that required serious work to a month or 2 back
