RE: Tip for ESL fanatics

Good they sent off the Sketch-O-Matic.
Now? Are there any PROPRIETARY parts? Stuff made custom for PSAudio?
Those things....maybe custom transformers......should be lifetime.

Caps / resistors / semiconductors / ICs should be nearly commodity and available....

circuit boards? Another issue altogether, so I hope you didn't burn up a trace or 'charcoal' a board.

I've got a few things....like the DAC from Cambridge Audio where the will NOT send of a schematic.
And they want a fixed fee for repair which tells me 'pure profit'.. HSU Reserch also closely guards schematics with all sorts of 'intellectual property' claims. Nonsense..
Too much is never enough
