In Reply to: RE: FINAL TALLEY - Clip lead Orientating Film Caps in SET Amp posted by drlowmu on August 22, 2016 at 12:14:40
jeff - was the 4uf dynamicap change done at the same time as the cap polarity business?
if yes - wouldn't that possibly color your subjective evaluation?
as well isn't it possible that everything interacts and that as you change the polarity of some capacitors then others might behave differently?
is it possible that now you have arrived with everything in the "correct orientation" that you could repeat the experiment and find that things have changed and that you may need to change the orientation on some capacitors?
in other words - if the 10 uf caps polarity changes is it not possible that the best possible orientation for the .68uf capacitor could have changed - since you don't necessarily use the foil orientation?
maybe they should be done in a certain order - IE large capacitors first?
a lot of variables here to manage - it'd take a genius to do it all in their head.
while jumping the shark - is it not possible that the cap orientation could have an effect on the correct amount of wire to use and vice versa?

Rage, I suggest you go and listen to your amps with components attached by clip leads. I am going to do exactly that; beats cutting grass.
cheers,

Friend, I would not hurt thee for the world...but thou art standing where I am about to shoot.
for the record douglas, I could not hear the 4uf dynamicap implemented the way Jeff suggests... so I traded them to jeff for some chokes.I'm trying to eliminate caps... and parallel runs of wire.
I want 80% return on 20% effort.. all this polarity, wire leads, bypass caps is too much tweaking for me.. I just want to listen to my stereo and watch movies.
sounds pretty good right now without tweeters if that is any indication of my hearing.
I'm also hooked on L-critical choke input now... I can even rationalize choke input being better based on DFs guidelines... (although he wouldn't agree!)
I just need heyboer to make me a 5H choke at 20 ohms that doesn't weigh a ton.

Good luck wid your project, they are quite nice to listen to I bet. You know what the circuit needs ideally. Less resistance/more resistance, or perhaps less capacitance stray to ground or what ever. If there does not look like a reasonable change in any of the desired parameters, and I don't hear any reason to do it except, 'it makes the amp sound ssooooooo much better' I tend to leave things alone. There are also sources I tend to ignore unless I see some underlying benefit to a tweak they 'discover'...as the usual state of affairs with such discoveries is that they don't understand what they have done.
cheers,

Rage,
Everything interacts.
I did the Dynami 4.0 Es next to the last, as the plate supply of the Driver tubes, to more easily hear what is right and wrong on the Driver tube's Rk bypass caps. The Drivers' tubes Rk caps were the only ones evaluated with Dynami Cap 4.0 uF Es in place.
Yes, wire is a BIG thing, and it IS mind boggling to attack, throughout the amp. This morning I was listening to one versus two strands of 14 AWG Mil Spec wire, connecting to the Finals tubes' Rk resistors. I am about to go from clip lead to optimized soldering in, and hear that next ( two 14 AWG instead of the existing one run ). Lotsa work, glad the Pioneer Elite Blu Ray player has a great remote controller.

One further comment Rage, ALL of the MANY small bypass caps were ripped out of the amp, and ALL orientating was done with the "larger" main caps ONLY.Yes, it does take a genius to figure this out AND / OR, someone who is average yet simply dedicated, highly motivated, and focused .
Finally, I would guess its repeatable.
Jeff
