Nakamichi PA-7 Power cable replacement/IEC conversion question


Morning!

I've just acquired a PA-7 and it's in great shape functionally & physically, aside from the attached power cable, the outside jacket is cracking and falling apart. Of course replacing an attached power cable is not difficult, and I will likely take it to Doug at D'n'A Electronics to get the work done, but my questions are:

1. Through the cracks I can see what look like 2 solid conductor wires, plus 2 perhaps ground wires wrapped in a thin cloth material, spiralled around the conductors, maybe a custom design? Is there a specific spec power cable I need as a replacement?

2. Is it possible to convert it to IEC so that it will take an aftermarket cable? I have a Pangea AC-9 SE that I would love to try out with the amp.

If there are any known mods/updates to the amp worth performing while it's on the bench, I would love to know as well! For those that will ask it is the first version, not the MK 2.

 

Cheers,

My local guy has worked on a few of these over the years. I'll post what he says when I hear back from him here.

Hard to tell from the photo of the NAK PA-7 if the plug is polarized. It doesn't look like it is

That plug is polarized; mine has a ground plug also, hence a three pronged plug

I have the MKII version built in 1990 and I also live in Canada. It does NOT have an IEC connection.

I suspect that the Canadian models did not have an IEC connector most likely due to CSA  (Canadian Standards Association) regulations as opposed to the era they were built.in.

CSA is the equivalent to UL in the States.

Mine is the same. 2 wires/connectors only. 
my buddy has a PA-5 first model that is setup the same.

@jea48 the one in the ad is just an example, it’s not mine but mine is the same.

looks like Nak changed their mind early on.

It is the first version yes. Here is an example.

Any answers to whether it’s a custom cable or not?

I’ll leave the technical bits up to Doug, just looking for an answer of whether it can be for or not.

Thanks.
