The "B" version uses custom hybrid modules for the inputs... and the CH1 and CH2 hybrids are not the same... so you can't swap a CH1 hybrid with a CH2 hybrid.
I think the A and B model counters are fairly equivalent in their sensitivity to input damage. It seems to be a lot harder to find replacement parts for the "B". _______________________________________________ time-nuts mailing list -- time-nuts@lists.febo.com To unsubscribe, go to http://lists.febo.com/mailman/listinfo/time-nuts_lists.febo.com and follow the instructions there.
