[R-390] Tube testers and other babblings

[Dan Arney]

The best tube tester you have is the R-390 itself. Plug n Play. One good 
set of tubes and a good set of spares should in most cases out live you 
with all things being equal..
 A dyna-jet was normally a TV tester. It will be fine to check filaments 
and general condition..
A TV7/B or so is a good tester but  kind of pricey for the occasional user.

Mix and match. There are certain positions that the 5XXX series tubes 
should be used in. All of the tubes are getting harder to get but in 
most  cases still available. There are some sellers out amongst the 
wherever that think they are Gold plated. If you plan on saving them for 
a retirement investment then my friend you are barking up the wrong 
tree. Maybe 3TF7`s or sort.
Current tube prices are a lot more stable than the stock market which 
could very likely bust its guts very soon.

Once the nasty caps have been done and the radio tweaked, put your tubes 
in a box in the closet and then quit fooling with the radio and enjoy it 
for many years..

There are guys on the list that  have had them running for 24/7 for many 
years.

AS you have heard if it works don't fix it.
Enjoy it.
