Isolation Transformers

I bought an isolation transformer from a fellow selling his home audio gear about a year or so ago. It’s a 12” cube that weighs roughly 60 lbs and has 8 plugs in the back. It was apparently used in a hospital. 
I have most of my gear including a tube preamp plugged into it mostly for protection purposes. It puts out a constant 124v which is a few more than what I get directly from the wall socket.
Anyone else using this sort of device as a “power conditioner” and what are the pros and cons of using one? I’m guessing delivering a constant voltage (almost) regardless of the load is the main advantage of this type of device but am wondering if it impedes full current delivery at high amplifier loads. Thanks.

@kalali,
Is that a loaded voltage or an unloaded voltage measurement? The greater the connected loaded the greater the VD (Voltage Drop) across the windings of the transformer.

Measure the voltage with the intended load connected.

^^^^^ Great question, and I think it was unloaded, if I remember correctly. I’ll take some measurement with preamp and amp up and music playing at moderate listening levels.

@jea48 given the choice between the hospital grade Tripp-Lite and the regular Tripp-Lite that you referenced in your post, do you have a preference?  I am only concerned with front end equipment isolation i.e. low power requirement.

@testpilot ,
Why? From what are you wanting to isolate?

I want to isolate both my pre and phono stage from the main lines to reduce noise etc. On occasions, I also get a ground loop issue.  I run large power hungry mono block amp and I don't want to go the large transformer route.
