Post by: Tone Junkie on September 03, 2021, 03:11:15 am

Anyone have the wiring diagram for this transformer its a classictone 40-18072 for 100 watt marshall. I seemed to have got rid of all my hard copies. Who would have thought they would go out of buisness. thanks Bill

The ClassicTone website was archived (thankfully) and you can find specs on almost all transformers/chokes here:
