How to upgrade a nondetachable power cord?

Either way you suggest would do the job, but if you want a really workmanlike solution, you need to install a IEC panel receptacle on the amp and plug your PC into it. That's how CJ would have done it.

Additionally, that'd allow you to try lots of different power cords. Oh joy!

The last time I looked into the "how to" of this matter, it seems to me there were chassis punches available that accommodate either 15 or 20 amp IEC receptacles. I'm sure you can find them to purchase, or (even better!) a repairperson who has them, and would do it for you for a small charge.

Alan, in the mid eighties, no one used detachable PCs except for portable or pro equipment. Certainly NOBODY used alternative aftermarket PCs, because there was no such animal.

If you needed a longer PC on your amp or whatever, you used an extension cord. And if the PC it came with was longer than you needed, why you coiled it up real tight and neat. That way you increased the broadcast range of the EMI it was radiating. Of course you had all your components grounded and were using coax-type single ended ICs because that's all that was available if you weren't in a recording studio and using balanced!

I noticed while visiting the Aural Symphonics website the other day that they make a special (?) adaptor for just this purpose called the Power Inlet Mod. Go to:

You cut the captive cord short and attach this adaptor. Don't know how much $$, and it's probably no better than Alan's solution.
