5/31/2019 ~ Love those eBay Bargains.The WRL Duo-Bander was a find on eBay and I couldn't resist trying to make it work again. In looking back at what it took to get this radio to "breathe again",  was not looking at individual circuit elements like resistors and capacitors; but circuit modules much like I do with my solid sate designs. 
It was most revealing that the WRL circuit designers used some very clever module approaches in their design and it was totally homegrown right in 'middle America". 
Following that thought it was soon realized that majority of ham gear in the period of 1940 to 1970 was designed and built in factories located in Ohio, Iowa, Nebraska, Illinois, Indiana, Michigan, Minnesota, Missouri and Tennessee.

Hopefully before they "pull any trigger" they give deliberative thought to the human scarifies that will result. I truly worry when someone has the audacity to call themselves a stable genius. Really?
I will never forget standing at a helicopter landing pad one day…
