Done a few mods,
Leslie I have a rough service 20w bulb on a clamp on the right, to the left is a wardrobe hanging dehumidifier. Centre is a hygrometer. Went in after a few hours and it was 22C internally and 16C externally. Humidity was 38% internally, 55% prior to heating cabinet.
BX3 has a 5v USB fan pushing air out over a 27W heater/dehumidifier combo (contains desiccant granules)
Both Leslie and BX3 have been coated with ACF50. That includes circuit boards on BX3 and power amp/metal parts aside from belt/o-rings on Leslie. ACF50 is used in military and aviation on airframes and electronic components to stop corrosion.
Should keep everything nice in garage.
First time I"ve had lid off BX3 and there"s plenty of space to mount my HX3 inside.
Using thermal synthetic covers, not cotton which would pull in moisture and hold it
