I have a wonderful DB680 which I decided to replace the tubes on (there was occasionally some 'popping' from one of them).
Anyhow, my son decided to help and took out the tubes when I removed the lid. Good boy, but....... I now have no idea which tube goes where?
If anyone can tell me which sockets house the two 12AX7 tubes, then I'll be fine.
Here's a pic of the layout before the tubes were removed http://s7.photobucket.com/albums/y28...er_media_share
