Best source of SG613 is junk sets. They either work or not,
dead shorted or OK.
Semis have an infant mortality. If it lasts a few minutes
its life expectancy jumps to near 100% for decades. So
if you got a Sony with a bad jug pull the SG613's &
? 2SC867's ? was it ? They are as good as new IMHO.
As long as you get any kind of raster they are fine.....
