I got my 1980's Tektronix months ago
One capacitor went dead (short-circuit) and took out a resistor when I first fired it up... I should have used a variac and slowly drove up the voltage....
I just now (today) hooked it up to my home-made rf sampler (I had to order a bnc jumper & wait), I still don't know what the hell I am doing, but I am close..
Don't give up DodgeRam. I know you can do this, you just have to learn what and from where to read, and to ask the right questions when you have the opportunity to ask..
This part worries me, wait a few years, build your own radio as a learning project... REALLY understand how they work first, before you even think about making a buck...
Otherwise those who know will not respect you & your prospect will fail..
Many good people are on the internet, & will help you, you just have-to show initiative and try, the reward of fixing your own equipment will come.. in due time. The purchase was a good step, but next time look into the various options you have, sometimes spending more is not better!
EDIT: If you want a peak reading meter, why not use an oscilloscope instead?
DOSY meters are better left for the user not the tuner...
Any meter can work as a reference point but once you decide to do your first "tune up" someone is going to laugh and walk away if you show them output on a DOSY meter.. j.m.h.o.
