Sir, tube pins ang topic. Hindi hito.
peace sir Efren.
Pero in fairness, masarap ang hito na prepared that way.
Very informative topic. Never did try to attempt to clean my tubes cuz hindi pa ako nagpapalit.
Wuestion, di ba ang WD40 is conductive?
It's alright sir just for the sake of discussion
, we pinoys are known for being resourcefull & creative, btw WD40 is basically oil, and oil is used as insulator (aside from being a lubricant, coolant etc.) in Meralco transformers, oil filled capacitors ( your tube amp probably have one), Vintage power x'formers use oil (in the form of wax or tar, oil has a very high voltage insulating properties.
Just don't spray directly especially at tubes while operating, WD40 in particular has a very low flash point, unless you want to incinirate your tube amp
, I remember I used to make flame thrower out of a can of WD40 using a lighter during "kakulitan" days of my long, long past youth
