Re: Restoring my 1960 'Burst... need HELP..!!
Oftentimes... overdriven tube amplifiers (e.g., Marshall, HiWatt, Orange) driving low-wattage Celestion speakers (as used by Jimmy Page at this show), will become hotter and hotter as the show goes on. And I mean power tubes that are RED HOT!
Most guitar players are familiar with how hot an amplifier's power tubes, transformers, and other components can get. However, some may not realize just how hot the voice coils can get in an overdriven speaker. Hot enough to burn your hand if you touch it.
After prolonged heavy use, the output efficiency (power) of a hot amp and speaker will usually suffer. Furthermore harmonic distortion usually increases. Speakers most often fail because they are unable to handle the high current from the output transformer and become very hot. This is know as speaker fatigue and can lead to a "blown" speaker.
All of this can result in a loss of brilliance, high frequencies, and harmonics. I believe Page's amplifiers and speakers are exhibiting this behavior towards the end of the show. This could be one reason his LP Custom sounds like it has more low-midrange character, and less treble frequency response.
