You can get a Composite Video Board from a seller in Canada on Ebay: https://www.ebay.ca/itm/124844441452.

Re: Which video mod for composite?

I think you have a 100K ohm resistor connected to the Emiter instead of a 100 ohm resistor.

Re: ZX Spectrums problems : diagnostic software ?

This the very same for Canada. I live near Toronto, Ontario Canada.
It is difficult to have to stay home as we are over 70 of age.
Fortunately we have a son that can help when needed that live close by.
Stay safe and in good health.

I will adjust the volume setting and see if that helps!
Any update on your problem
