multi meter ekakin transformer eke voltage eka check karala balanna keeyak enawada kiyala,madinam transformer ekak danna wey

Tikak hitapan mama kiyannam karana widiha.

1. IC 2 ta Heat sink 2k set korapan. (around 60W each IC -> require bit larger heatsinks. never use thin aluminum sheets. Always use thermal paste)

2. Buy 28Vx2 (28V-0V-28V 5AMP) transformer. better if you can get 6AMP or higher. but dificult to find)

3. Look terminal block near big capacitors, middle terminal is 0V (center tap), others are 28V each.

4. There is no speaker protection circuit here. so atleast connect speakers series with 3A~5A Fuses. Also include main fuse (1A 250V)
