Lemmie tell ya true story.
Some customers came in with Ebay bought amps they loved and used, but wanted me to look them over for anything that could be upgraded.
All the components looked OK for the price they paid, but the OPT's looked unnervingly like regular split-bobbin power transformers. I put the amp on the equipment.
80Hz-12KHz at F3.
Hrm.... that frequency response looks familiar. Oh, the OPT has a number on it! *Googles* ... *finds match* Guitar output transformers like AES sells
So, I add NFB enough to flatten them to 30Hz to 18KHz or abouts, IIRC.
The customers did a collective "EWWWWWWW!". Having them open on the bench, I clip out the R/C network and they go, "YEAHHHHH!"
I hand them my report and they couldn't believe it. I had to re-sweep them in front of them.
They went from the "Best thing for under $300" to now sitting abandoned under my bench.
The moral of the story - if you like it, don't dig too deep. Like mystery meat sandwiches, you might not like what you find
