Sega Amp problem on channel right

[wasspat]

Hi,

I turn completely nuts with this

On my Naomi Universal Cabinet, i've lost the sound on the right channel so I've try to repair the problem ... I thought it'll be easy.

The amp is :
838-13616

I've :
- control all capacitors : all good
- the fuses 3.5A : all good
- the continuities of all cables in NUC : all good

It seems the problem is common on this amp.

Thanks for your helps or any tips.

The LM3875TF is a single channel amp. That's why there's two of them. My guess is that the other one is blown.

If you try to swap it, be very careful taking it out. They are soldered from both sides and it's really easy to rip pads and traces.

Thanks Nem, I've start to remove the LM3875TF (and indeed it's a pain in the xxx ). i've ordered new amp and I'll comeback with results.
