I got a TSL-100, which is UK-rated for 230V. Now that I have moved to N-America, I am looking for a way to convert the amp to 110V (or 117V per Marshalls' spec). Looking at schematic TL10-63-02 Rev4, it seems that all you have to do is rewire the W4 & W5 connections to respectively W1 & W6. With these red wires just being plugged on the designated tabs, it seems like an easy fix. That and replacing the F1 fuse with a 4A, of course. The only other difference I noticed on the schematic is the type of power switch, but this maybe just because of the light therein. Unfortunately, I can't think of a way to remove this switch without breaking those rear plastic tabs which are bend in place. Anyways, will this do the trick?
