CHECK OUT THE WIKI The purpose of the wiki is mainly to allow you to find information on instruments, either from either
- The model number
- The function(s) listed below. Some instruments have multiple functions - for example, the 4195A is a VNA, spectrum analyzer and an impedance analyzer. Therefore the 4195A is listed in multiple categories

Re: Transformer data
You can judge by bridge rectifiers diodes. They all get hot. I think it is 15-20 amps for +5v rail and 5-8 amps for +20v rail.

Re: Using an 8903B to analyze power audio amp
Yes, you are correct, but the 8 ohm or 4 ohm load has to be rated for high power, especially if it is only cooled by ambient air. For a 10W amp we use a 100W non inductive restive load. You also need
