drlowmu,
I am not following you on this? Why would a tube preamp that uses a few milliamps of current need thicker wire than johnmicheal used? Hey, I'll try it myself but it doesn't make sense?
First of all, welcome to Hi Fi Visions Forum !!!
Your thought process
seems logical, but in actual practice, it is faulty, if you seek the highest fidelity, in terms of definition and
dynamics.
I have experienced this in my builds, over and over and over again, for at least 20 years of the last 40 years building tube circuits.
You may or may not be able to hear this in your builds, depending upon what other assumptions ( with possible errors ) exist in your executions.
( See the wiring in the DIY Forum's on-going SE DC 6005 thread, and notice precisely how I executed wiring. It is all very audible - at that build level. )
In this thread's preamp photo, do you see how there is absolutely NO local capacitance, no B+ storage on the audio boards, where the circuit is TRYING to play music. No, the regulated energy supply is six inches away, interconnected by P.U.ny wiring.
In my builds, film capacitors of
high quality are only 1/8th of an inch from a triode's PLATE resistor, or 1/8th an inch the tube socket's pin.
What method would you think is superior for delivering instantaneous energy in
pulsed play back of NON sinusoidal music wave forms. and events - six inches of thin wire or a quality film cap, located within 1/8th an inch of the use-point ?
I am referring to something like a pulsed drum solo with cymbals??
An even more interesting question, what do you THINK is the
instantaneous PEAK current of a 12AX7 circuit idling at 1 mA??? The need for a
great power supply, and wiring execution, with such low current tubes, is surprising.
I say these things to you, meaning absolutely
no dis respect, but in an honest attempt to answer your question. " An inch of bad wire can ruin the musical experience. "
If you want to send me lotsa good below-deck photos, and a good schematic with voltages, I would be happy to suggest simple things for you to hear and try out. Private Mail me for my direct email address. I did this wire excercise with a high end USA audio Manufacturer, over the last two months. I would be glad to have you speak to him, on what he heard.
My suggestion would be to use Military Specified wire, m22759/11 specifically, readily available on eBay, etc., and at surplus prices. ( Apex Junior, Surplus Electronics, below ). I usually employ 16, 14 and 12 AWG as audio wire sizes, singles and paralleled combinations, depending upon circuit position. I am actually mailing some of this wire, those three AWGs, to Thane, Marharastra, in about an hour, from my home in the USA today !!
