Okay I will check this - what about the board - are there any other components that will have been damaged by the burning out of the above mentioned resistors?
Thanks for your help
possibly, but did you set the bias?!
Yes I did it as per the manual
Many thanks
I set the bias as per the manual and left it to settle - what other components could have been damaged by the burnt out resistors R4, R16, & R17 please?
Also - you say that the transformer could be at fault - is this the only area or could it be an input level issue - any help is welcome
Many thanks
:?: ?
Hello,
Probably most of the transistors on your board are damaged; like also some resistors. you will have to measure the 5W resistors and other resistors that seem suspecious.
I suspect you used the amplifier without proper(fixed?) heat-sink or with a too high supply voltage.
Did you adjust the bias with speakers attached?
yes
The manual says connect them afterwards… :!:
