Fender de Luxe, PR 246, 2004
Only used , not abused, domestically, ie not bumped around ina van at any
time. Mechanically broken dome end of GT badged Sovtek 5881, neat circular crack. Black deposit around a jet out of the envelope matching a black deposit on the metal "protection" cage screwed to the cab back panel. Gripper function around valve base was fine. Not obviously valve/cage touching, but close, I will reposition this cage 1/4 inch lower down. Is this a recognised design/construction failing perhaps Russian 5881 a bit longer than 6L6. -- Diverse Devices, Southampton, England electronic hints and repair briefs , schematics/manuals list on http://home.graffiti.net/diverse:graffiti.net/ |

Or a vertical bar from top to bottom to prevent the panel flexing inwards if pushed up against something. Have repositioned the "protection" cage down 1/4 inch and bent the horizontal part of the cage downwards a bit to give about 3/4 inch clearance from the bottles when no flexure of the back board. -- Diverse Devices, Southampton, England electronic hints and repair briefs , schematics/manuals list on http://home.graffiti.net/diverse:graffiti.net/ |
