Solidoodle 3 heated bed blew

It happened just before I went to print. i started using a cloth to get the board up to temp faster - it reached about 100C and I took the cloth off, then I noticed the temperature precipitously dropping. It wouldn't come back after that.

I emailed support and tested the pad with a multimeter from the terminal and got 0 ohms, so the whole pad is definitely shot (I think). I've been doing a lot of research since then with a lot more luck, and I'm thinking about upgrading and going with the qu-bd silicon pads - specifically the 6", which would fit in the footprint of the original heating pad. Would attaching it to the aluminum bed and insulation with double sided kapton tape be sufficient? I saw your post on making a bed platform that can be scaled for the 8" pad, and I might do that later, but I'm a little scared the platform will deform. If I'm upgrading I'd like to be able to operate the bed at 120C which seems to be recommended for maximum ABS stickiness, but specifically because it's past the glass transition point.

I'm still iffy on power supplies. I think I should just go small for now and buy a 1x12v 15A supply and a solid state relay, which as a bonus doesn't seem to require any soldering. All the future modifications I want to do rely on having a working printer anyways. Does all that sound alright?

12v 15A for a 8" heated silicon pad is the minimum.... i advice to take something like 12v 20A or more..
