Compatible Power Cord For A Vintage Kustom K200 Bass Amp Head

[Gary]

Looking to replace the original 2 prong power cord with a 3 prong ground plug.
The metal plate on the back of the head reads....Output= 100w RMS...Primary= 120V...
FRE= 60 Hz...Input 1.8 Amps.
Where can I find a power cord thats compatible with the above information?
Thanks.

Google says 19 gauge or better. I usually just hack the end off an IEC cable since I have them laying all over the warehouse. 1.8 amps isn't a ton of current, so most any power cable within reason should be able to handle it.
