(Pic above - sorry, don't know how to attach it)

I've got a gig tonight and thought it would be a good idea to buy some nice new tubes from the lovely people at Watford Valves. I whipped out the old valves from my Ampeg SVT-6 Pro and didn't note which valves went where. Yes, I'm an idiot, I know.

To cut a long story short, I need to put the original valves back in.

There are four 12AX7 valves and two 12AU7 valves.

I've hunted high and low for a schematic - called Panic Music, spoken to Watford Valves, and left a message with Loud Technologies and no ones entirely sure what goes where.

Can anyone help??? I've attached a picture of the empty valve slots!

Thank you folks!!

Steve

This is probably too late to help you, BUT....

The two sockets labeled J12 and J39 on power amp get 12AU7, all the rest get 12AX7.

Thank you sir! I found the right placements at the elevent hour. Although, when I played the gig, my sound kept breaking up and crackling - I've tried wither the old tubes again today and the problem's the same. Don't suppose you know what the problem might be? Cheers, Steve
