[@balthromaw6305]

5:40 Anyone else notice his mislabeled connections? his left is right .... and his right is left.... silk screened on the board is OR and OL (output right and output left) Also.. this is a CLASS A amplifier. and DO NOT put the 5V regulator on the same heatsink as the power output transistor. the potential between both heatsinks are NOT common ground, He got lucky as the super glue is acting like an insulator, but don't do it... keep it separate.

[@ricclark6977]

Also the odd biasing of the whole thing, it seems to work in the video but I have doubts about how long or how stable the amp would be in the long run. And with only 12v, maybe you could push 4w into a 4 ohm speaker before distortion becomes noticeable; assuming the transistor is biased at 6v.

brother what about temperature how much that transistor can heat-up ? can we play it non stop 5hurs or more ?

This one is for educational purpose for beginners. These transistors heats up and required big heat sink for proper heat dissipation. Also you required two separate heat sinks for this circuit. If you are making for personal continuous use then make the 3rd or 11th from latest videos on my channel. 3rd is with d718 & b688 and the 11th is with c5200 & a1943.

As per your video I have made the circuit. But not working. First time it worked later not working. Only beef sound comming

[@ScienceTechnologyExperiments]

These transistors are most sensitive. You might touch wrong voltage connection directly to transistor. I have made two separate heat sinks because both collectors are directly connected with the heat sink. So both heat sinks are having positive voltage. The 5v regulator ic is also on heat sink which is negative voltage. It should not be touched with other heat sinks. Hope you understand.

[@gopinathann8261]

As per your suggestion separate heatsink were given and USB connection made by giving separate connection
