WARNING: Tube/Valve amplifiers use potentially LETHAL HIGH VOLTAGES.
Building, troubleshooting and testing of these amplifiers should only be
performed by someone who is thoroughly familiar with
the safety precautions around high voltages.
Any ideas on what sort of paint to use to retouch knicks and scratches on vintage black chassis from the late 80s to 90s. I was thinking of automotive retouching paints available in a pen/marker form.
