I tried this but with no effect. While trying it I noticed, to my great confusion, that the noise is greatly reduced when I hold my hand around the tube, especially at the front. I guess this means I should buy a Faraday cage for the tube, or is there any other way to remedy this? And if the solution is a Faraday cage, does anyone have any suggestions on where to buy ones that fit 6SN7?I unfortunately do not own an AM radio, though thanks for the tip, I will try to borrow one to test!
