Ribbon cable inside amplifiers

I have been looking inside amplifiers on google images, newbie here…wondering if ribbon cable inside the amplifiers is a cheap way for them to build…I was looking at Pass Labs seem to have a lot of ribbon cables…


Years ago when modifications to Sony SCD-1 SACD players were in vogue I substituted harnesses of Audio Consulting soft-annealed silver wire for ribbons in the digital and analog domain to good effect.  But it's too much time and effort to repeat such experiments today.

@dgarretson - Nice to see you my friend.

I think those are fun experiments to do,  honestly, but I wouldn't do it on a megabucks amp as my first trial.  Given the advent of streaming, and 1 PCB construction I wonder how much of that is even possible with modern designs?

oh man…seeing Erik defend Pass I had to pinch myself to make sure I was awake…just kidding…

@silverfoxvtx1800 stop trolling. Angela amps looked interesting to you but Pass Labs amps look odd because you saw a ribbon cable? You don’t think it’s odd to see gallons of melted breast implants dumped over the shitty point to point spaghetti that gilbert puts in his amps? Now he’s wearing a skirt and calls himself Angela? Thanks bud, I’ll stick with Pass.

Those ribbon cables are most likely used for the front panel meter, That meter measures current at the output stage so it appears each wire in the ribbon picks up the voltage from a transistor (probably across the emitter resistor) to do the conversion. Since there are a lot of transistors, it is much neater (and cheaper) to run circuit traces to the transistors and then gather them at a connector for a ribbon cable. Or else there would be a bird's nest of conventional wires if they were soldered point to point..
