Guys would anyone post correct DeLuxe Mistress voltages?
I have the V2 (1979) type with on repair here, with the UA741CP input chip. Thank you.

All right, here are voltages on the repaired, working unit. Someone may find it handy.
I measured the voltages in the Filter Matrix mode, so the DC doesn't swing.

26.7mA  AC draw from the transformer (18V)
14.7mA DC current draw through the 78L15.
Power dissipation on the 78L15 is 183mW.
