The 545A I think has a fatter ( over the length) CRT, something like 8" diameter. the 545B has a slimmer CRT approx 5" diameter.

What plugins/ vertical amplifiers does it have? These may help identify what version you have as will some pictures posted here.

The manual is free from either boatanchor manuals or elektrotanya, also lots of info and pics at Tekwiki.
