Am I correct that at 20ma. a string of 5
Yep, you will have to string several together.
To bias my 6N6P's cathode, I used six Crees (csd01060E-TR) with an STPS2150 to get just where I wanted to be, around -5.4V
If you go this route, buy a few extra.:-)
Those Crees are the TO252-2 package. They're rather tedious to work with due to their size. Once done, it's a tight compact string of diodes.
I found stringing that many TO220s was not realistic and they wouldn't stand up.
Hope this helps.
Cheers,
W
