Hi all
Great group.
I`m well into a resto of my Polysix.
I`ve fitted a KiwiSix board and psu.
I have replaced the paired transitor
with a 2SC1583 45G.
I`ve replaced the opto coupler with a VTL5C9
and I`ve replaced the three ICs 17.18 and 19.
When measuring IC18 pin7 to TP5 I`m still
getting -13v.
Any suggestion on what to change next would
be much appreciated.
Many Thanks
Dave
