Studio Pre Valve Location Identicifation please ?

[japster]

Hi,

I'm looking at changing a few valves in my Studio Pre.

However having taken the top of I'm a bit lost as to which valve is what ?

Can someone identify from my photo graph which is valve V1 - V4 (I've identified V5 as it's a different type i.e. 12AT7)

Cheers,

hey,

looks like the front row left is V1, ( closest to the input) and V4 is closest to the GEQ, and the one in the back (V5) is the reverb driver so:

Actually that's what I thought, but wanted a 2nd opinion.

Convention is from input to output V1 - V4 (V5 for reverb)

I've got the schematic already but it's very difficult to read, does anyone have a better one ?

I'm finding it rather difficult to follow the circuit

there are a couple on tubefreak.com for the studio pre, did you see them?
