CPC6128 Volume low

(1/4) > >>

minwah:
I have a bit of a problem with my 6128 whereby the volume out of the internal speaker is very quiet, even at full volume.

I have compared to another machine which is several times louder. I have also tried the speaker and volume pot from the 'loud' machine to rule those parts out - it made no noticable difference.

The sound is correct, just quiet. Seems like there is an issue with amplification...just wondering if anyone else has encountered this?

Thanks!

TFM:
Maybe it's worth to exchange the PSG (and give it a socket this way). Good luck!  :)

I'd be tempted to check around/replace the audio amplifier chip first,  before condemning the AY to the dustbin.

TFM:
Probably a good idea, thought it goes out directly (from memory).  :)

@minwah


Try headphones on both machines.
If the sound level is the same look at the Speaker amplifier in the Tape Circuit


Good luck
