Hiah Al,
Lets do it one by one :
What gauge is the wire inside the fuse ?
A: Very small.
All of Jeff's most recent personally-built DIY amps use TWO AC switches, The second AC switch is a fuse and / or thermistor "bypass" or short-out switch, so I don't need to have them in the circuit when I am in the room with my amps, and I am doing serious listening.
What gauge is the wire inside the fuse ?
A: See above.
What gauge of wire is used inside the transformer ?
A: Lowest gauge possible.
Its an large core 18 pound device. It sports an under 9 Ohm "ultra hi fi DCR " high voltage winding secondary, from either end of the winding to the center tap. The 125 VAC primary, the entire winding, is "about" half of one Ohm. The wire I use is 950 mA. continuous capable, what is yours ??
What gauge is the wire inside your tubes ? What difference does a tiny fraction of an ohm make ?
A. The tube design is fixed, we work with it as thoughtfully as we can.
ps Why didn't you use black wire ?
A: With the new wire, having a low AWG rating, high silver content, and wide bandwidth, its likely good enough performance wise to use black insulation colors, and be better than anything else " I " have used previously.
Now you know what I am doing. What are you up to in the UK these days? Have a great day.
