I do continue to wonder if a long path through an electrical storm, from the driver plate to the DHT grid, is perhaps bringing something to the sonic smorgasbord.  Is this run anything special in the way of wire or shieldiing?  Should it be?  Would making it shorter change anything?

I asked myself the same question. The wire I run is long. The distance between the driver and the output state is 14” and I made is a 3.5” longer and I decided the run non-shielded wire and not direct but around the places where I feel would not be “inductively dangers”.

I consulted with a number of people who feel that they “know” and they stressed that this DC-coupling wire is super significant. They might be right but I did not feel that it is all credible as the loaded me with other “super significant” comments that I personally degree. So, it is very difficult to say what is what. The DIYer might run their mouths about any subject and since I personally did not hear what result they are getting and since they never were in my place we can’t correlate what Sound we consider “acceptable”. So, I have idea what to think about the wire for DC-coupling.

From one perceive it shall be very important as it goes to grid. Anything the goes to grid is critical. If you remember I wrote that changing the path in which my fix’s bias was supplied voltage to 6C33C grid did impact sound. From another perspective the signal already quite robust after the driver stage, so go figure…

I took a regular 22ga pure copper wire with Teflon jacket and juts run it. I do not write DIY books and do not need to be “correct”. If Sound is acceptable then I less care about the “minor things”. The sonic result that I got so far did not make me worry about picking the “little things”. So, I kid of sold for whatever is there, sure it will be more fun to run a vintage Dominus in there… but I do not see myself spending time to do it.
