" The [chassis] heat sinking so provided is more
than adequate, as the 337 dissipates less than
2.5 watts under worst case conditions."
I put the EFB in an SCA-35 some years ago, with the 337 mounted to the chassis as called for in the article. I've got maybe 100+ hours on it, and have never had an issue with heat.
The Texas Instruments data sheet for the 337 rates it at 125 ºC, with a built-in thermal shut-down.
Perhaps DAC's 337 was damaged during soldering, as he has speculated.
