Dynaco/Telefunken 12ax7's sell for $50 - $60 apiece nowadays, $200-$240 for 4 Telefunken 12ax7's.
This is the 1st PAS preamp I've seen with a "white" top cover. (There are 2 more "white" PAS2 selling as I'm writing this).
Following are the pictures posted by the seller. I will post some hi-rez pics in a few days.
