[Lafayette] HA-800?

Actually, I tend to disagree. The Lafayette gear will perform to specs
given that components of the equipment are up to their specifications.
Shorted and leaky caps or resistors out of tolerance will degrade any
piece of equipment including American made stuff. The Lafayette receivers
are no more difficult to align then any other receiver. If you lay a
typical Lafayette receiver schematic next to a typical Hammarlund or
National schematic of comparable equipment, you'll find very similar, if
not identical, circuits in many of them. It was a lot easier during those
early years to lift a design then trying to reinvent the wheel.
Unfortunately, back then, the initial new, up to spec components, were
not designed for 40 year life, so deterioration of components became
common in time even without the big stresses of heat, humidity, cold,
etc. of basements and garages.

My Lafayette HA-460 and 410, 6, and 10 meter transceivers, still perk
along during sporadic E openings and worked great during the last sunspot
peaks.
