Default tingleing featherweight

I have a 221 featherweight which I love...only problem is that I can feel like an electrical vibration on the machine table. I took to a repair shop and asked about it and he said he did not find any problem...so I have been working on it and it works fine.

Anyway I still feel that it should not be happening. When I place my hand in the harp it stops vibrating so I don't know?? Do any on you have any ideas ??

It may be the polarity of the power cord. First thing to tryis unplugging the machine and turning the plug over.

If Ken's suggestion doesn't work you'll need to go deeper. The other thing I can think of is you might have a bare spot in a wire causing a partial short.

I have the original cord but bought a new replacement because of that problem..and since it is new one prong is wider than the other.

Sometimes, it's our old house wiring making it happen.

I would carefully evaluate the wiring on the machine. Then next your house wiring like CD says maiinly because your service man can't find the tingle.

It could be anywhere but in my experience it's never been a polarity problem. Here's why: you cannot choose polarity on Alternating Current (AC) - it cycles 120 times a second.

From the link above:
Polarity results from the fact that an electrical circuit has a negative and a positive pole. Direct current (DC) flows in one direction, resulting in a constant polarity. Alternating current (AC) flows half the time in one direction and half the time in the other, changing its polarity 120 times per second with 60-hertz current.
We've talked about this several times here and there are always suggestions to turn the plug around which is a bandaid at best - it probably nudges the short apart.
