Wow.
Yes, I had always heard the stories of that happening, but never saw
one. Mine is almost hard to see, it didn't cave in the surrounding
glass--just a very slight stress crack and a little inverted pimple
where the hole is. Filaments still good. Sweep tubeshate em even

Hi All,
I followed the link in that other post to an archive of Ham Radio Magazine.
This because I too was curious about how the digital alternative for
the Drake FS4 frequency synthesizer, as mentioned in this post, looked
like in those days.
I had a very good time reading!

I was in contact with Mr Stein, and am likely the poster of said found
reference on this list. He did send me the data electronically. I thought I
had a copy on an old backup/archive, but after spending several hours looking,
it is not to be found.
As I recall the big thing was differe
Today I put a totally dead R-4a on the bench,replaced the fuse and off she
went. The rig was fairly clean considering its age. The rig lit up and got some
audio out and all functions seemed to basically work. Cleaned the chassis of

I rarely use Deoxit in tube sockets unless I have reason to believe the
sockets have oxidized and are causing issues. If you do use it in tube sockets
its best to dip a round toothpick in Deoxit and insert that into the individual
sockets, giving it several turns. I have also applied Deox
I do the same as Garyapply small amounts to the pins...easier to see
how much you are applying...rather than putting it down the sockets.

I have found that 100% DeOxit dries more slowly than the 5% stuff
because the latter is mostly carrier. So allow a little extra time
before powering up, especially with pots. A few hours should have
been enough, so it seems that you applied too much. I almost always
use the 100% stuff but I avo
How I learned to be paranoid with cleaning agents:
When I was a mere teen-ager, I decided to clean the mode switch in my HW-101
with some "contact cleaner" that my brother had brought home from work. I hosed
the switch down well, waited a few minutes, and turned the rig on. The mode
switch smoked.
Is the lesson, never trust your older brother?

No, I already knew that one ;)

Hi all,
Do we have any collectors of old morse straight keys in the group?
I suddenly find myself with a an original well used/abused WW2, J41A (
which is an unusual piece) to dispose of. This was from a 90+ yr old lady,
and I don't think she wanted to give it away, more like she's disposin

In addition to the "wooden stemmed tightly woven Q tips that are
made especially for electrical cleaning" mentioned by Dennis, AE6C, I also
use the brushes listed below. A drop of DeoxIT on either goes a long way.
These brushes are great for cleaning 7 & 9 pin tube sockets:
