there is a proposal by tweak audio to do this among other tweaks and was wondering if anyone had experimented with this. maybe installing a small film cap across the led would make the same difference, thanks
A forward biased LED is probably quieter than any of the transistors or resistors in the circuit. The impedance is low enough that a film cap bypass does nothing other than cost money and take up space. There may be psychological benefits, but any electronic ones are dubious.
YES !!!!!!!!!!!
it will sound brighter , because every LED is stealing brightness* from amp!
*that's the reason why I'm always puttin' several LEDs in my projects - brightness setting mechanismus

Apropos of the subject, when I first made FW amps with the blue LEDs, I
ran them at a couple ma current and they were fairly bright. This resulted
in comments about the high frequencies which went away when I dimmed
them down. Similarly, red and green LEDs elicit different perception of the
sound in a number of customers.

Finally! Something I dont have to worry about! I still havent installed the leds!

Waiting on the following line being added to Pass DIY site on F4:
of course feel free to use what ever "audiophile grade" led you choose in your designs.

In defense of the OP, if you brought this topic up in the Curl thread, you might get different opinions.
everyone knows or should know that cryogenically treated quantum purified LEDs are the quietest.
A guy at Woodstock, back in '67, told me, the world was soon to have zillions of tiny-plastic-light-bulbs EVERYWHERE !
"I have several hundred 'proper bulbs' stashed, just in case...man"
In case of what ? I asked...
...no reply.
Wish I had his cell #, he might have a good 'tube-pile' as well...
Si.
PS...Round here, our mate Andrew said...
" There's no LED on it ! How can you tell if it's ON ?"
I said...
"Sound comes out."
( we stuck a label on the foot-switch of his fuzz-box later...
...which said - This is NOT a foot-switch )
He was slightly 'annoyed', even though there was no red LED fitted.

I use orange leds, which, of course makes the ss gear sound tube like and blend with my tube gear.
Now, with a tube amp you simply must use original glass bodied LEDs.
The plastic cases of the semiconductors in SS amps are a better match for the plastic bodied LEDs.
LOL !!!!!
