Quote from: troublerat on June 17, 2009, 12:33:55 AM Forgive me for being a little thick on this thermal grease /heat sink thing. What we want is to pass the heat from chip to the heat sink but not the electrical characteristics of the chip itself. With an + - power supply. The pos volt connected to the pos. pin the neg. volt connected to the neg pin. The surface of the chip and heat sink are the grnd ?
Quote>"The "Tab" (metallic back of the chip case) is connected to the V- (negative voltage) pin,"<
QuoteSplit supply: V+ , V- , and ground; output directly connected to speaker. You *must* use grease *and* a suitable mica, to electrically insulate them,
QuoteI have an trans. with 24 -0 - 24 secondaries and I"m going to use an 25a bridge rect. with some largish caps [between2000 and 4000 uf]
