Us folks who have a bench full of 8-digit display test equipment to calibrate within .001 of 1% in compliance with a cesium-rubidium time/frequency standard would be "technicians" and not your garden-variety hobbyist. Save the Lafayette, Eico, Heathkit, and Elenco for the hobbyists. If technicians were to try and calibrate the hobbyist brands with their 8-digit display gear, it would only be for entertainment purposes to see how many digits remain at 0. I'm sure at least 4 or 5 digits would remain at 0.

5 tube circuitry aligned to perfection... only to end up listening to low entertainment value broadcasts!
