Powering on my Hughes & Kettner GrandMeister Deluxe 40 guitar amplifier after changing the tubes
1 year ago

Tonight on April 16th 2023 I changed the power tubes in my Hughes & Kettner GrandMeister Deluxe 40 guitar amplifier because the O.E.M. Shuguang EL84 power tubes were wearing out as the filament was deteriorating normally over the span of nearly 3 years since I bought this amplifier new from Sweetwater in July of 2020.
I bought a matched set of four Genalex Gold Lion EL84 power tubes that I carefully installed myself while using paper towel to prevent touching the tubes so I wouldn't get any of the oils from my hands onto the glass of the tubes.
