is there any problem replacing the original power supply 50n06 with 65n06? i have 6 out of 12 50n06's burned up but i dont have any here but i do have 65n06

You may have to reduce the value of the gate resistors. What is the value of the original gate resistors?

 

[bikerboy87]

they are 47 Ohm

 

[Perry Babin]

Those will work.

 

[bikerboy87]

alright thanks Perry

1 more question. Is it normal for U4 on the output board to be fairly hot when running? Amp is up and working got clean sound just wondering about that

 

[Perry Babin]

Which driver board does it use?

 

[bikerboy87]

in the bottom corner it says 81013 v1.0 also these capactitors are hot and the red coil of wire

 

[bikerboy87]

the amp is still up and playing music though been bout 30 mins now i play it hard every few min

 

[Perry Babin]

The op-amp nearest to the edge of the board operates at very high temps. The two transistors in the yellow rectangle should be replaced. They have a very high failure rate. They run much hotter than the op-amp.

 

[bikerboy87]

is it normal for them capacitors to run hot also?

 

[Perry Babin]

I can't answer that question. I've never had one of these in the shop. Before I'd worry about the caps, I'd replace the two transistors. They could be causing problems.

 

[bikerboy87]

ok then ill get them replaced thanks

 

[bikerboy87]

1D is MMBTA42 correct?

 

[Perry Babin]

Yes.
