Hi everybody,

Well this is my first message here, this forum is fantastic.

Well  I have a Sharp compact x68000 Redzone and I have a problem with  fm audio I change all the capacitors smd of the pcb, but I have the same problem I hear the sound very low  and distorted in my Sharp if I put the headphones until the end I don't listen nothing I must to put the connection of the headphones in the middle more and less to listen something.

I would like if anybody have the some problem and if is posible to resolve.

Thanks a lot

Replace the Op-Amps.  In the Compacts they fail 95% of the time.

I never did figure out what was wrong with my system. I sold it to a local guy who is going to take a crack at repairing it.

I suspect one or more transistors have failed.

IMHO it should be fine as long as MC3403 is mentioned in the part number. Please someone correct me if I am wrong.

That's a regular quad opamp in SMD SO14 package. Original is a MC3403, compatible device are TL074 or LM324
