Default Wiring example

Hi folks,
here an example of some kinds of wiring I done with ordinary switchgear wire.
The first both pics showing the input panel and the line driver of my homebrew pre-amp. The third pic show the harness of the line driver stage. The both right ones are showing the wiring in my MC-3500 power amp clones.

Such neat wiring can be a pig to debug/fault-trace, and can encourage coupling between different circuits. I do my best to avoid it!

Hi DF96,

yes it could, but I spent lot of effort to avoid it , because I personally like this way of wiring. My invested time to finish such kind of equipment is not an issue. I made drawings of the wiring and give all wires a running number. In case of a fault its easy to trace each single wire vom its start its destiny. In several projects I had to make one or the other cable harness twice, because of a false running wire. But most of these bundles contains only supply , ground, heater , control or balanced audio wires.

I never put high impedeance wires into my cable looms. For other sensitive wires with lower impedance I take screened ones . In the added pics of my previous page there are lot of balanced circuits, which will not an issue for coupling high frequency loss.

I worked in a company way back in the seventies. This Firm produced equipment for german brodcasting and the post office telecom in small quantities. We did the wiring in the same way, without any troble at all.

Here are another sample of how I made it. You see that the plate wires run separate from the harness (the black sleeve left of the valve sockets), the heater wires are screened avoid spreading mains hum into the circuit. These pics showing the interior of a 10W Guitar amp I build a while ago.

That's quite reminiscent of the old Quad and Leak stuff- I seethe with jealousy.

That's a lot of unsoldering and changes. Probably better to scrap the PCB and build point to point.
