don't recall if extender boards were available for this receiver---I never
saw them in my spares lockers on any of the ships I sailed on.

I'm not sure we're writing about the same radio.
The Mackay 3031A doesn't employ extender boards because
the modules are connected by ribbon cables to the rest
of the radio. You can remove an entire module several inches
away from the radio and it will still function because
it is connected electronically.

After several years, I've not had to replace the
lamp -- only the memory battery.
