Classic gear from yesteryear; vintage audio standing the test of time.

Not according to the late Allen Wright

If we're talking about the same preamp, Allen Wright said:

"That unit's design was a direct ripoff from me"


Link to Allen's Asylum post is here and also below.

Here's the Last PAS phono (with David Vorhis corrections indicated), line stage and filament supply schematics, if anyone is looking for them. I may have the Vorhis / Jung regulated B+ schematic too, if someone needs it, although I showed it to Allen Wright once, and he wasn't too fond of it.

Note that for C43 and C44 in the filament supply, I use two 120,000 µF caps. I've had several people tell me that much capacitance shouldn't make an improvement, but it does.
