I recently picked up a really nice looking PAL 800XL on Ebay in the UK. This thing looks mint but it was sold with an issue with the audio volume being low. I did some research before buying (on here) and it looked like the likely candidate could be a dodgy LM358N audio amp chip.
So I took the risk and bought the machine and ordered some new LM358N chips I then took the old one out and replaced with a brand new one. And the result, the audio volume is no better, well maybe it's a little better. It's also slightly louder through the RF modulator and the video port but nothing drastic.
I've reseated the POKEY just in case that made a difference, but it didn't.
So has anyone got any ideas what else I could look at to the problem?
Thanks in advance for any help.
