Hello! I have had two LM3875 ICs laying around for a while, i had used them before so i tested them today and they worked

so i am putting an amp together

Here comes some pics and a video: http://hififorum.knaak.dk/Tekko/annat%20skit/ Unfortunately a leg on one LM3875 broke off but i managed to get a wire to stick to the remains of it but if it comes loose minus 38 volts will fry one speaker.

Its still playing good, tried to blow it up today, the 3875:s got burning hot but it just continued to play. After maybe 3-4 hours of bad mistreatemt i gave up. LM3875 seems indestroyable.
