I have a pair of 8000P's I picked up last year for a song. At first they sounded muted and had some funny buzzing, but the longer I played them, the better they sound. Apparently they had not been used for a long time and they just needed "exercising". I received the rebuild info from Claude, and even purchased all of the capacitors for a full rebuild, but the way they sound now, I am hesitant to touch them. Instead I am lusting after a beautiful pair of 9000P's for sale on Craigslist, trying to justify buying them. Oh - yes I live in an old house with high ceilings and hardwood floors.
