During the first years of manufacture the ampliers/recievers in the
Armstrong 600 range used a thermal delay relay to avoid a surge when
the unit was switched on.
These were expensive. And they were one of the main failure modes
which brought sets back for repair. One of the reasons I avoid
physical relays. I replaced them in later sets with a better PSU that
simply didn't need a mechanical relay. Over the following few years it
was quite clear that this had a big impact on the reliability of the
sets.

The kind on the left - I bet.
You lose you bet on both counts. :-)
I did not use them. I replaced them with something else.
Nor was that type used.
Slainte,
