Adding DC Heaters to a Marshall JCM800 2203x ...and all about HEATER SUPPLIES!!

A 2203x needs it's power transformer replaced so we're taking the opportunity to put in 12V DC heaters alongside some high gain mods to make the amp dead silent at idle.
Full rundown here on the different types of heater supplies, bench time showing how to implement the PT change out and new DC heaters. Also featuring a special guitar in for a try out!

All tones in this clip are from the 2203x with my mods in place and with the DC heaters implemented.
