Look at the power board mounted above the Convergence board.
find the 6 pin connector and measure to chassis ground for + and - 15
volts, + and - 45 volts.
If any of these missing replace the corresponding rectifier diode.
If all missing except the +23 volts, after unplugging AC power remove
convergence yoke plugs on the side of the convergence amp board and re-apply
power.
Did the + and - supplies return? If so troubleshoot the convergence amp
board BUT don't rule out the power supply board.
I have seen the +- supplies appear OK with the yokes loose but still a bad
power supply
