i got a quick question im trying to find out what goes in r2035

the pink spot in the center.

The originals were 13 ohms. Those were overheating and damaging the solder connections. Later amps used a 1 ohm.

 

[theoddguy]

great. thanks!

Hey Perry,
I had to resolder this resistor (13ohms) in mine as well. Are you saying I could just swap it out for a 1ohm without changing anything else?

I know of no other modifications but I have not compared two amps to see if there are any other changes.

 

[salsunny]

OK, thanks.

the amp plays now but the outputs over heat. i traced the signal back to the lm5110.
the wave output coming out is really bad. would there be anything else i need to check before i order parts?

 

[Perry Babin]

Is the input OK?

Does it have supply voltage?

 

[theoddguy]

everything running ok. op amps and rail voltages are right. the lm5110 looks to be going bad u2000 or whats feeding it. on pin 2. trying to trace the signal back to the card now.

It probably goes back to one terminals of the 74hc74 IC. Confirm that it has supply voltage. Also confirm that it has a triangle wave into the clk terminal (pin 3) and a square wave out of pins 5 and 6.
