Audio Amp Resistor and Transistor & Heatsink ?
Hey guys i am building this amplifier and while i ran into a few problems here and there, i have ran into a problem that i cant seem to trace or reason.
The amplifier circuit i am build was the ESP P3A
**broken link removed**
The problem at the moment i am having mainly is resistor R12 gets so hot that it burns and smokes. I originally thought there was something wrong with the transistor placement but everything seems correct as i have checked a few times.
An interesting observation, is i get sound from the output which is actually pretty decent, the LED blinks to the sound, Transistor Q7 gets a bit warm but i believe thats normal as its the output driver. Interestingly transistor Q8 is rock cold not even warm a tiny bit, as a output driver i was wondering why its not even warm- maybe that linked to the burning resistor.
Any thought or suggestion would be helpful.
Thanks
pete
