Yes. They work very well (even more so the diamond tipped fitments) but
take a god awful amount of time to process any useful areas.

The 'select 1 of 10' ATU would seem a grade 1 mechanical-electrical
juggernaut of switches, relays?, screening cans, adjustable inductors
(roller coasters?), variables caps, connectors and knobs. I wish you a
interesting journey :-).
During a radio phase I think I also tried 'em all. Concluded they're all
much-of-a-muchness and finally settled on a 2 component "L". (The human
ear's 'Db' response seems to make a bit of a mockery of equipment technical
spec's :-).
