Q............PP Ultrapath

yes it's one of my ODD questions again.

so here it is....can you use ultra-path at the out put of a PP amplifier ?

I don't see why not. You would need one cap for each output tube from the transformer CT to the cathode.

However I see not advantage,and lots of dissadvantages based on this:

Ultrapath = Ultra Simple...Except that it's not

Which follows my real life experience with similar topology using sand.

yes it would be very difficult to set for good

but my father (ex leak tech) did some tests on ultrapath and he was not all that impressed by it's ability to fight peaks in B+ etc.

although according to him what it did best was to allot the work load between the resistor and the capacitor better than "in parallel to ground".

and as i'm one of these people who believes that you should only give speakers what you can hear and no more work than that..................i like resistors (in the power amp)
