Tried adjusting core 3 to fix 533 bug permanently.
R/W voltage was 62 can run it up to 66 or so before [High low?] speed checkerboard complains at [110V or 10V?] on +10 can also set it to 64V
High speed checkerboard, BLT all ran with core 3 1F & 1[K?] +10 A+B margins 10V low [11 or 12 overwritten]V high ! (this seems unlikely, but the margins seem to be getting through

AUDIO OUTPUT SYSTEM DOWN BECAUSE OF BROKEN REG. POWER SUPPLY. TROUBLE APPARENTLY DUE TO SHORT ON EXPOSED PC BOARD FROM DANGLING CABLES.
OBSERVATION: EXPOSED POWER SUPPLY CIRCUITRY AND UN-FUSED POWER SUPPLIES BOTH ARE GREAT KROCKS!!
