Could any one help, I have a new valve tester, and need settings info for an EL34 valve or a 6CA7, I am not very up on internals of valves to set the switches on the tester. This is to test several marshal amps and others can anybody help me!!!

Hello and welcome to the forums. Perhaps ask this in a section other than Introductions, not everyone looks in here.
Welcome John,
Welcome your come to the right place,
Just by chance I saw your request for info on a T. Tester.
Sylvania's aren't all that common, and I believe there were only a few model nos. that they made; but I do have copies of operation manuals and tube testing data for a few of the models.
Well most important is: What is the Model No. of yours? Any options/revisions? Serial # sometimes helps ensure that one get the right manual and info for the actual unit.
I have info (.pdf files) on the following Model Nos.:
Model 140, Model 219, & Model 220
If its not one of these; with a little research I'm sure I can find it.
Never, pay someone for manuals or datasheets for obsolete test equipment (unless your looking for an original), there's just too many resources, DIYers, HAM radio enthusiests etc that 'live' by the flow of free info and ideas. Heathkit is becoming an exception to this - copyrights were bought/renewed for profit/greed.
More than happy to send you any info you could use; over the years that's how I've acquired my library.
Marshal Amps....Cool!
