I have built 2 tube monoblocks PAs.
I wanted to listen to them and sonically decide what sounds better. I have about 4 variations to try out. One is with or without GLOBAL negative feedback etc. My issue is I'm having a hard time remembering and comparing what I'mhearing. Is there a way to record the output for later playback, making it easier to decide what sounds best?

Do you mean acoustically or electrically?
I would just play one for a week or two, then go to the next version for another week or two.
There's no point in trying to instantaneously A/B them. that's not how you listen to them.
You want a long term reaction.

Yes acoustically. Hearing the same song back to back should help identify differences, at least that's what I'm thinking. I don't have to guess at what I thought it might of sounded like.
That sort of stuff is done on YouTube all the time. You'd need a decent mic though.
But A/B comparisons are of little use. That's how bad speakers are sold in stereo stores.
Bad speakers can sound good in a brief, carefully set up comparison, but will be intolerable over time.
Same goes for other types of audio comparisons.

I would DIY it... It should cost about 5 cents if you have a cheap place for resistors...
The thread about how to use REW has an example using 22k and 2k in series to make a 10:1 attenuator.

You will be largely listening to your listening room over anything else, unless it's expertly treated.
This: The two small resistors are the 22k:2k, the big one is the load for the amp. If you use the speaker as a load, you could omit the big resistor.
I don't think the pic you posted is relevant to the thing you want to test 🙁
