[R-390] 3DW7: A 3TF7 Tubester

[Drew Papanek]

Hello David,

Runs cool and regulates great?  Sounds like the ultimate ballastube 
replacement!  I am envisioning a switching regulator or phase control type 
of arrangement possibly with controlled rise and fall times to minimize 
noise generation.

All of this sophistication in a 3TF7-sized package-now that's an 
accomplishment!
