PH3.

Hi,

Now that I did a search on it the PH3 actually does exist.

ARC PH3

I doubt the circuit diagram is publicly available and if it were it shouldn't be posted here in any way for copyright reasons.

If, however we can assist in a problem you have with it we'd be glad to help...right guys?:cool:

Cheers,;)

Of course we would. But we don't need to. Looking at the site you gave, the PH3 is quite new, so our Chinese friend's pre-amplifier is still under guarantee. He doesn't need a diagram, he just needs to get it fixed (under guarantee). And, if he wants the diagram, he can simply trace it from his example. It's not as if valve circuits are complex.

It's odd that our Chinese friend hasn't said why he needs a diagram...
