OK Sams 2146-2 is the same style & year.
It uses 9-181-02 & 9-186-01
Cap I mentioned is C3496 & seems to be on the 9-181
NOTES
Early 9-181 used IC sockets, they were eliminated. You had to move the
IC's & 3 color outs to the new board. PIA
There were 2 types of start circuit. One used a transformer on the 9-181
the other a multivibrator on a PCB mounted on the hoz out heat sink.
9-186 comes mounted PCB only. You dont get the heat sink, small
parts etc. ( watch for overheated hoz yoke plug ! ).
BTW I have 2146. If you cant find a free one PM me for price MUCH
less than sams & a real quality printing, not a crappy PDF or Xerox.
