In Reply to: RE: That's not exactly what I said about wire! posted by gusser on November 20, 2014 at 12:29:27
I have to ask, how in Dennis' world view is the stock wire, used on the lead outs for the secondary (including center tap) of the filament transformer winding, any better than what is being referred to as "the wrong wire"?
To anyone answering this question, keep in mind that those wires are in the signal path as is the wire between the plate of the driver tube and the grid of the output tube or the ground buss wire.
Are those wires somehow better than the "ACME wire, sourced from Lowes Hardware stores" that Grant used and was told that "one inch of the wrong wire can totally ruin the sound of an amplifier"?
There's no technical consistency in Dennis' argument, just a bunch of BS.
It's not just that I disagree with him technically. Dennis disagrees with himself technically.

It looks to be a stock filament transformer, so I doubt the wires are anything more than stranded copper.
Perhaps this part has been upgraded/replaced by something better.
"Perhaps this part has been upgraded/replaced by something better."
I would assume so and Dennis confirmed that below.
My point is, at the time the picture of Dennis' amp was taken he was using the stock lead outs.
I don't personally think that those short leads would make any audible difference to start with but then I'm not a big "believer" in wire differences.
IMO, If 'one inch of the wrong wire ruins the sound of the whole amplifier' then the design of the amplifier sucks and needs to be re-designed.

Of course it has been.
I got into pulling the leads out of chokes & transformers and replacing them with Siltech wire.... I do that to speaker drivers as well, and to a whole lot more. This, of course, greatly improves their bandwidth and impulse response.
(Open up a JBL horn-driver, re-wire it with Siltech and THEN listen to the highs!). Use WonderSolder!
Dr. low mu, then, brought that idea (of replacing leads with TCSS, etc.) to you all so you could get more out of-- especially-- ordinary, commercial chokes.
I have had some chokes built to my specs lately-- they have silver leadouts designed-in. (more expensive).
These are very nice, but one can, if sufficiently handy, modify commercial chokes and get very good results. Leadouts can be re-anchored with G.E. Silicone-2. Let it cure thoroughly before you pull on that new wire!
Also, while inside the choke's insulating materials, make sure you re-insulate your new wiring against the winding stack-- just depending on its insulation alone won't make the choke reliable in long-term use.

Many moons ago, I owned Spendor 9A. I decided to modify the existing stock zip wire that connected the drivers and replaced it with high end speaker wire.
