My 802 series 1 bass alignment filter went tits-up last year. I had previously replaced a handful of resistors and electrolytics but heat ultimately cooked the board. I can no longer read the op amp part numbers, and don't have a schematic.
I always loved the sound of the 802 S1's on classic prog rock and traditional/bebop jazz. Driven with a good vinyl front end and Aragon 4004MK2, plenty of slam when called upon.
I liked the bass better with the filter installed; I miss it. I am an electronics engineer and am quite willing to build my own. Any information would be very welcome. The approach taken by Arupg sounds like right up my alley. pdbrooks0@gmail.com
