I used to buy normal transformers for my amps. Never had any complaints about them. So I was wondering if there is any benefit in using "audio-grade" transformers. Is it, soundwise, a big difference?

This image is a Toroidy, will come a week ago. It came without magnetic shielding because I asked (increased another 2-3 cm in diameter). It has a small mechanical noise by opening the lid of the box.

Comes with electrical protection, grounding wire, and the center with expoxi and mounting flanges.

You should ask with flexible connections, but comes standard with solid core wire.

Got a crazy idea, would two of these boards with 100 x 1000uF be nice to use in my F5T v1?
Will it give a better sound or performance instead of picking 4 big, say 47.000 uF capacitors?

probably yes

under condition that these 100 aren't drek

Not good quality, operational but barely, poor, bad, cheap, junk, etc...

I also have grounding issue, small buzz. I tried Zen Mod's tricks. Now buzz is in left speaker only. Amplifier sounds better then expected . Zen Mod do you have any more tricks? Buzz as you said fet still works. I broke fet while drilling to enlarge hole for screw.

Glued with epoxy steel J B Weld before installation. Seemed to work well. I hope I can get the screw out later as I did not want to wait for the glue to dry .Greedy boy has no patience.

Should have waxed the screw first.
