Thanks Dave,
Most software faults follow the same arc. The difference is I sort of know what I am doing there ;)
So what should I look for next?

I'm don't understand how a phase anomaly would prevent the tone control from affecting the sound, though I can see how it might remove some of the bass frequency, which is also part of the problem.

More confused than ever :?

It completely explains the (otherwise incomprehensible) chip choice, and I'd be very interested to know what exactly they are doing to get a supposed 'stereo' effect. Oh, and poor LF response could be simply down to caps drying out.

I'm a bit suspicious of the tone control doing nothing at all. A simple fault would suggest only one side being affected. Also, no stereo effect at all sounds a bit strange. I wouldn't be surprised if it turned out to be something daft like a hairline fracture in a ground track.

Just because you know what I'm talking about, it doesn't mean I do!

Did I bolt you up Will? Sorry if so, I thought you had made an offer?

Now that's an expression I've not heard before - must be one of those Northern things :lol:

Anyway, I'm quite happy with the idea.

Oh! Yes, getting "bolted up" is being volunteered/pressed into a task that you did not want and is not actually in your job descrip'!

Not to be confused with "fitted up" which is something our police never do or ever did.
