I did a bit of research on huff-puff stabilizers a month or so back
and the one that seems to be preferred for the TR7 is DL1SDQ's

Incidentally, after a good bit of research on

color of the TR7 to redo my sticky-paint MN2700 cabinet. I spent
about a half-hour going over hundreds of color chips without being
able to decide which one was the closest. They said that most colors
have names, presumably
because of limited lead length on
the caps or to reduce inductance. Or, perhaps for some other
reason that isn't obvious but turned up in the prototyping
stage. Drake engineers seem in general to have known what
they were doing.

If you have a really badly regulated line voltage perhaps
using a line regulator like a Sola transformer would be a

Gary,
Since I cleaned it I knew where it was. I noticed that the zero adjust
affected the meter's reading of the bias also ... so I wanted to get it
set correctly.
Thanks for your help,
Richard Palmer

The S-Meter is Zero'd with the cleverly disguised ZERO
for my upgrade so
hopefully I will be on the air with it soon. FWIW I am the proud new
owner of a Jackson 648 S. The tube chart is dated 02/70 and it handles
all my tubes.
So thanks to all here for the help, words of wisdom and encouragement.

The law, in its majestic

model. I have spent hours squinting at pictures trying to count socket
pins. I am burnt out and am looking for help in finding just where to
look. I have no idea if post WWII testers even test 9 pins, or if all 7
pins are of the same size.

The law
I recently acquired my first tube radio station. A TR-4/RV-4/AC-4.
Everything seems to work as it should. My question is one only a rookie
would ask, and I'm sorry to ask but I have looked everywhere I can find,
without any luck.
Should the AC-4 have rubber feet on it? Mine does not and when
Ok. Thanks all. I did not know the AC-4 was securely mounted to the
chassis of the RV-4 with screws. I was just sliding it in there. I see I
have the threaded type mount power supply. I also see that the feet on
the RV-4 are nutted. So I'll try to screw the RV-4's rear feet into the
bottom of
The TR-4 has 6 rubber feet (sorta). On the rear there is one in each
corner and in the front there are two stacked in each corner. This
raises the front to an angle. The RV-4 has rubber feet in both corners
up front that look very similar to the ones on the TR-4. And in the rear
corners there
What is the going price for a working power supply for an L4B?
