Good point... Man, I surely appreciate all the help on this site... You guys
are great!
I'm just a beginner with the older stuff and have always been so envious of
my older brother, WA5ZTE and my Dad W5SNY (silent)...
They started in the old days and built and repaired their radios...
I wasn't a ham until the 90's...
And so I'm wanting to go back and learn from the good stuff...

It's certainly not a bad idea to have replacements if you do end up needing
them (you will, someday), just not advisable to swap them wholesale as

you get it running it's easier to compare results through performance. Tube
testers are fine for a quick look and for showing some obvious faults, but
I've had two instances in the last 2 years where tubes tested great and
showed no problems, but didn't work properly in the set. I've also had
receivers that worked great despite having some tubes that tested low on the
