[R-390] 6DC6 Replacement

[Roger L Ruszkowski]

Oh no!  I read the ENTIRE post!!!  Is there a cure for this?  How long do I
need to breathe tube-heated air before my brain is fully cleansed?  Do I
need to sacrifice a virgin 26Z5W?

Scott,

I am so sorry, I tried to warn you.

You will need at least 4 hours over your R390/A
a little less over the R390.

Do not sacrifice a virgin tube.
That does not work.

Find a least three gassy tube and
roast them over a proper zippo flame.

When you get the blue glow out of all three tubes
you will be "clear".

What's a tubester?

(Aren't there "tubesters" for the 6DC6?)
