Thanks for the advice.
I think the electrical connection is OK because the distortion only occurs with specific point of the music. On the Deer hunter track, it is at around 2minutes 50 sec. I will play the track in another set to determine whether it is a recording problem.
I found that some of the screws holding the 12P frame to cabinet is loose.
More testing

Skin effect, self-inductance, things like that that don't amount to anything at audio frequencies, but are important at microwave.

It's cheap for a start, which is nice. Skin depth for the thinner types should also pretty much exceed wire gauge, pushing the HF corner higher in frequency -skin effect is a non-issue at audio frequencies for any wire you're likely to use, but no harm in shunting it higher providing you don't make too many tradeoffs elsewhere to do it. Solid core is good -less surface area to corrode & potentially increase resistance over time.
