[Boatanchors] Way to go me!

[Adam Liette]

Thanks for the replys. I was afraid of this, but hey it happens. The worst
part is these NOS tubes haven't been in it for 2 months, hi hi. Oh well. I'm
just trying to figure out what it will take to fix, and sounds like I'm
receiving some good ideas. Although I need 6, I'm glad to not be dealing
with some of the other tubes! Seems I should have another set, but not sure.
I'd swear I had 2 extra sets, one now used of course.

73 and Thanks again!

Adam, N8YD

Your 35LR6s have joined the Choir Invisible.  R.I.P.
The blue glow is ionized stuff burned off your tube elements.
The "growl" is the power supply wondering why it has
metal-ion gas-filled rectifiers where pentodes should be.
It will destroy itself finding out, if you leave it on very long.
Pull the tubes and see if the "growl" goes away and you
have B+.  If not, the bridge diodes followed the tubes
into Linear Heaven.
Sorry, OM.  35LR6s can't be easy to get.
I'd bet some folks here have ideas on how to
change them to something more pocket-book friendly.

73 D.S.
