Replacing AC cable on older amps and pre amps (Non IEC)

Sure, but why?

Get an isolation transformer and do it right.  Much more effective.

Good question. My preamp is from the 70's and the amp, late 90's. Both are quality pieces that I will be keeping but they do not have IEC inputs. Both have stock (Audio Research) cables on them.

I've upgraded IEC cables on other components and it made a HUGE effect on sound. I also added a Richard Gray Power Company box and that also made a HUGE improvement. Say what you will about those, I'm not going to be taking it out of the line. =)

I'm exploring what difficulty or problems I would run into by putting in new cables in the older pieces. I have no intention if installing IEC inputs on them, just new cables.

@wolf_garcia If you select the 10 gauge variant, the price goes up!

OP. Just make sure the new cable isn’t too thick for the small hole of older amps.
And make sure it is:
1. Not solid core.
2. Mains rated.
3. Grounded

also is your poeer amp also on the Ricard Grey or just the small stuff ?

noromance (really? none?)…anyway, I'm way into inexpensive well made stuff…actually I revel in that sort of thing, and I might actually buy one of those cables if only because they look pretty cool. Also, I've replaced AC cables in old guitar amps here and there as I hate being electrocuted (note also that you can't have electrocuted without "cute") and it's always worth it.
