which one is more common. You are probably correct.

I can only say that they fail often. We have
replaced lots in
our 11/70. Luckily we have had spares.
Sometimes the failure has been rather catastrofic with blown
components. I think these modules run quite hot since
discoloured pcb:s are common.
I think we more often see failures in the H744(0) modules, but we've had
failures in both, yes.
