Tonelab

[Titch]

I've got an old Tonelab now (not an SE or a LE)
Can anyone tell me where the tube trim is on this ?
I've looked at the service manual and it says "tube test" but there is no maention of how to trim the tube

Through the tiny hole in the bottom.

Thanks Nik
I saw the hole but can't see much inside let alone a trim pot.
Which screwdriver do i need ?

[Nik]

I used a really tiny jeweler's screwdriver. But I've been told it's actually a really tiny allen wrench that's needed. Whatever. The screwdriver worked for me.
