Thanks Mark that definitely confirms the location

BTW.. on an unrelated topic, that board has a Recom DC converter installed, will it still fit in the case or does it stand too proud of the board? I was intending to install a Tracopower on the board but that one might be a little too tall to fit?

I believe it's mounted horizontally in the same manner as when fitted to ZX80's.

Have a read of this thread

Also have a look at this recent thread where there is discussion and pictures
And ‪Pictures of my ZX81 fitted with a RECOM 5V Regulator‬

thanks Mark, the last post in your thread shows the Tracopower not much taller than the socket next to it so I'll try a test fit before soldering it in place to see if it's nessasary to install it on its side.

@Tezz, yeah, I have not tried a Tracopower in a ZX81 yet. So even I don't know

I have and adopted your horizontal method with a dab of glue for extra stability.

Which type did you go for?

A nice shiny red Traco reg with a dab of poundland super glue!
