Must be so. That makes most sense. I'll try that on my SE/30 motherboard when i find and working body SE or SE/30, mine's analoque board is toasted for good.

What's wrong with your SE/30 Analog board ?

As long as it's not the flyback, it can probably be repaired unless the PCB is severly damaged of course...

I'm in the middle of recapping the analog boards and PSU's of my SE series now.

I already did my older Compact Macs ( 128K to Plus ) last year.

One must not forget that the capacitors on the Analog board and PSU are as old as the one's on the logic boards.

When I recapped my analog boards I discovered several large radial caps that were dried out, some leaked a little at the bottom.

In the end they are over 22 years old so I guess it's time to replace them.
