My friend recently purchased a LD MKII from the recent massdrop. However, he purchased the 220v version instead. After researching it, we learned its possible to wire the primary windings of the transformer in parallel in order to accept 110v. After doing this the blue LED would light up upon flipping the power switch but then after a few seconds the fuse at the AC line blows. We took the unit apart to make sure everything was grounded properly and then put it back together. When doing this, we broke a wire off the 2W10 rectifier on the board (we did not know this at the time). The amp no longer blew a fuse, but the sound was very distorted and quiet (as expected from an issue with the rectifier). After reattaching the wire, the fuse continues to blow. The fuse also blows without any tubes attached, and we tried using slow blow fuses as well. Any help is appreciated. Thanks!
