Hi Mike
Swarfega works well for dissolving and removing the black goo from more sensitive plastic parts and material. But acetone is better on metal flywheels and pulleys.
I believe cellulose thinners will also dissolve the black goo. But be careful of using any of these aggressive solvents around plastic parts.
I wonder about the value of replacing a PM erase head with an electronic erase head when there are so many cheap cassette recorders around. (I have about 10 for sale), unless it is purely for the technical design challenge.
