hindi mo kelangan palitan ang power transistor nyan tulad ng cnabi ng isang mama.kelanman hindi nagcreate ng static noise ang power transistor. suggestion ko lang start with the transistor(s) but disconnect first the power and preamp section, if it is disconnected and the noise stop, it means nasa preamp. to make sure gamitan mo ng oscilloscope, andali nyan ah.... regardsssssssss  |

Tama para ngang nag piprito, basic lang kc alam ko sa electronics e  ano kaya pwede kong i check na parts dun yup pwedeng ic or small tannies, yung to-92's, outright replacement yan, kasi sa tester hindi mahuhuli yung noisy transistor.... |

crackling sounds malamang galing sa preamp
malamang galing din sa tone control----mic preamp kung nakavolume ang mic ----
stage by stage ang gawin mo bro
matagal na pala ang thread na to
overcooked na ung pinipirito

yup, 10000ufd/50volt caps implies rails of +/-45 volts max unloaded.....75watts at 8 ohm loads per channel is possible...
