How do they all compare sonically??

I am quite surprised that nobody has claimed yet that it "gives depth to the soundspace" , that it causes "sonic bliss" or that it cures bad breath, although now that I think of it, the last claim *can* be verified.

I don't know I'm not a big fan of goop. I use Kerafol pink and they don't require goop, seems to have a very good heat transfer co-efficient and reusable for those of us that FET roll

Reusable? I thought they were designed for single use?

Modern ones are single use.
The mid 1850's ones were washable and reusable.
Of course as thick as a party balloon.

Back to thermal insulators, after a few dozen thermal cycles under high pressure, the rubbery material tends to take a fixed shape, matching surface imperfections.
In theory you can pull and replace them in the *exact* same position, which is sort of iffy.

For DIY use, I have had good luck with using automotive Anti-Seize compound on Transistors and CPU's and the thermal transfer is quite good. It is cheap, only $5-7 for a large tube, so if you waste some, it is no big deal. Also, the transistors "un-stick" themselves easy if you have to remove them (great for car amps)

AN adhesive I use, with also good results is COPPER RTV sealant, not the regular kind. On projects I want to be semi-permanent, that stuff is awesome.

Default Where to buy 247 mica insulators

Hello all,
Very interesting thread and I have learned much reading your experiences and preferences. Thank you! I am an old school tech that would prefer to do things the traditional way with mica and goop. Unfortunately my supply of 247 style mica insulators is dwindling. Can anyone here point me to a reasonable source to replenish my supply?
Thanks!
