Heathkit sa-5010 u-matic memory keyer...

[Multi-Volti]

The problems I had with those at Heath was the LED's were insanely
heat-sensitive - we heat sinked them when replacing them- and the pcb traces
'lifted' when soldering extremely easily...and I never had either of those
problems with any other Heath product.
