I'm not exactly crazy about making my own tubes, but I do like to make a =
pc board now and then. Can you tell me where I can get info on the 'silks=
creen " method making pc boards. It would likely be a big improvement ove=
r what I've been doing with a magic marker and ferric chloride. thanks =20

Subject: [AMPS] Making tubes
Greetings Group,
=20
I will ask this question at the chance of being made to look ignorant!
=20
With the high price of tubes, I wonder if anyone has ever invisioned a ho=
mebrew project to actually make the tube from scratch? I know that it wo=
uld be a little more than the average ham is used to working with but why=
could we not use something such as stainless steel tubing and come up wi=
th a decent power transmitting tube. After all, someone once did that!
=20
We all know approximately what is needed and some of the group, I am sure=
, may have worked for places such as Eimac etc. and have a lot of knowled=
ge of what goes into such a task. =20
=20
Sometimes things like this is MUCH more difficult than meets the eye and =
on the other hand, some things are dirt simple and just appear to be diff=
icult. Like making pc boards from scratch--some would not think of it an=
d others like me can turn one out from drawing to board in 30-45 minutes =
using the silk-screen method at the kitchen sink.
