MCM Electronics, amongst others, carries various clutch
felts. I don't thik
it's so much the thickness as the density and possibly some sort of additive
to make them stiff.
I have tried MCM (actually, that is my supplier of choice), and using
assorted different premade clutches that are similar... as well as just
buying assorted felts, and even a clutch rebuild kit (comes with a dozen
different felts)... I have just struck out on getting it right.
It has gotton to the point that I am not willing to just randomly try
parts anymore... I have sunk around $50 into "trying" and struck out...
and we are talking about bringing back to life, cheap, low quality, 2
head, mono VCRs... in my book... not worth the continued experimentation
costs. When/if I find the correct part... I will buy a dozen of them, and
fix the 5 units I have (and keep the others as spares)... but until
then... they have been religated to plain old TV duty.
