Still use it to tune up my 67 Camaro.
There are still a few Heathkit and Eico items in a closet. I remember a Heath oscilloscope. And a 5 tube 30 (?)watt Eico amplifier built from a kit. Real beast, must weigh 20 pounds or so. Wouldn’t think so looking at it. Then again, maybe I should open it up, might have stashed so gold coins there.
