Yeah, I do have a multimeter.
I was going to have a look over the board at the weekend and get the multimeter on it to see if I could spot anything, but the battery has gone in the multimeter.
*sigh* nothing is ever simple!

Hmmm... No luck with the new chip unfortunately.

Re: AY sound issue with Just Speccy 128k
Yeah, no sound at all from that, until about 60 seconds in when I just got a loud blast of static.
I found an AY chip for £5, so I’ll see if that fixes anything when it arrives.
Will let you know the outcome, thanks for your help!

Re: AY sound issue with Just Speccy 128k
Great, thank you. I already had to send my board off once as it wasn’t working when I first got it. It was quite costly and postage to France took an absolute age... So I think I’ll try and get hold of an AY chip from somewhere. I do have one in my Speccy +2, but unfortunately it’s not socketed and ...

AY sound issue with Just Speccy 128k
Hello there! Bit of a long shot, but here goes... I bought one of Zaxon's Just Speccy 128k boards a couple of years ago, and have used it a fair few times for playing games. However, I've only just spotted an issue with it, in that there is no sound from the AY chip, and sometimes a little bit of di...
