Internet's a wonderful thing - the other day, I was oogling the 5f6 Bassman, and find early on, an article that describes briefly, a "legendary" 5d6 Bassman that never made into production and is apparently extremely rare and valuable. The article said that no schematic for the 5d6 was known to exist. During that same oogle session, I found a link. To a schematic. It says it's a 5d6 Bassman. Can anyone shed any light on this? Ever see or hear (about) one? Anyone able to read schematics who could say yes or no, or offer an opinion about any differences?
