We managed to find a small tantalum bead capacitor with legs that fits in this space nicely. A touch of glue for stability and the problem is solved permanently.

Got them from Maplin, which might be tricky now.

But something like this should do it:

Cheers Andy.

Have you had a play with temperature calibration? Do PKN have any instructions?

If you go to temp calibration menu and when it says "enter password" press both jog wheels in then up and down on both sides...

We have put these capacitors into old PKN amps as replacement, there is just 3mm room so therefore the 2.5mm thick component:

This problem has been eliminated several years ago. Normally the temperature calibration never needs re-calibration.
We have several 'running in the field' XE4000, 2500 since 2006 without need to touch anything.

If you put the capacitor 'in the hole' , you have a little bit more than 3mm, as a small capacitor can sit inside the hole between the wires.

Thanks. I'd also be interested to know if we can upgrade the firmware of these amps, mine are all mismatched. Perhaps there is a UART exposed somewhere?
