Hi

I seldom argue against Dieter ;-) but my experience from restaurating
old synths says: NEVER use an adhesive tape on electronic pcbs or cables!

Though it may take some time (a year or longer), the ingredients of the
glue will start to dissolve plastics or similar synthetic materials.
Especially capacitors are really endagered.

Also surface leakage currents may occur after a certain time, because
the glue collects dust, and the dust collects humidity...

If I really need to insulate pcbs or similar against housings I use
simply paper.
