5U4GB Solid State Replacement
I've never used a purchased solid state replacement, but in days of old many
of us tried
a do-it-yourself replacement. Most had good results. I didn't. I don't
recall using a dropping
resistor as Ed suggests, but it sounds ok. What I had problems with was the
solid state
diodes I was using had a much sharper cut-off (reverse current cut-off) that
generated
a little RF hash that interfered with weak signal reception. There were
others that experienced
the same thing. I was not alone. My RME 4350 ran hot, alright, but propping
open the hinged
access door on top helped a lot. Ed, what did others do to stop the sharp
cut-off hash?

I have seen the solid state replacement using the octal base for the
tube. I have a Hammarlund HQ 145XC that uses it, and it runs hot after
an hour or so. Just wondering if anyone else has used this replacement.
I found it for $9.99 on Tubedepot.com.
Thanks
