Thanks Kees,
One of the great aspects of building these units
is re-living the era(s). For example, in 1963, the year of the
HBR-11 introduction, I was probably in my last year of grade school or
first of Jr. High. The Dave Clark Five and Beatles were just
emerging. I didn't own anything nearly as sophisticated as the
HBR-11.
Quite a difference from the QST construction articles from
the 20's, 30's or even 40's.
