Hello and welcome to the forums. Perhaps ask this in a section other than Introductions, not everyone looks in here.

Default 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!
