Quark 125B works, but stops after 3 minutes...

If you are considering doing the Quark "mod" be aware that this will likely void your warranty and prohibit any on the house out of warranty repairs.

I just recently got back a Quark that I had to send to S&T. It had a note from Frank attached to it and it said that I should send it back in again, if the thermal pad comes loose again, because they won't be honoring the warranty on any Quarks that have had the cooling modification done.
