Yes I wonder about the wisdom of running all those wires in parallel, close to each other.

One only has to look at the Bruno amps to see that pretty wiring doesn't necessarily equal great tone.

Do you mean "inductive" coupling?

No, I meant capacitive coupling via all those parallel wires, but the big loops would also lend themselves to inductive coupling.

Well, it might be pretty, but zip tying an electrolytic cap to a power resistor doesn't seem like good practice.

I'd hate to have to replace a tube socket in one of those amps.

reminds me of Jons Dickinsons amps, which I have seen in person and they look lovelly and sound lovelly too,

I have built a few with similar style of wiring without any issues, lower gain of course.

but strapping a power resistor to the cap is probably not that great, even though that resistor may not get that hot

Thanks. We are talking about the same thing - changing voltages in parallel wires affecting one another. I tend to look at these as inductive because the varying field in one wire induces a field in the adjacent wire.

That has to be the nicest point to point I have seen. With all the unused terminals, it would also be easy to modify. That one I like.

Actually, I don't believe we are talking about the same thing. The coupling of signal or transfer of energy between two parallel wires is parasitic capacitive coupling. Inductive coupling is a completely different mechanism and involves a magnetic field interacting with a coil or loop. These are not at all the same.

You are correct - they are not the same. Let me say it more explicitly: If we are talking about currents in parallel runs, we also have to consider inductive coupling.

The B-field associated with a current changes with the magnitude of that current. If that varying B-field intersects an adjacent conductor, it will induce a voltage. It does not require that the conductors are in loops. That is a first principles example in most any E-M textbook.

Here's an example of how to deduce the difference between capacitive and inductive coupling.

If you have ever seen colossal's builds he has the nicest clean builds I've ever seen and his PTP were fantastic. He doesn't post many of his builds but I get to see them.
