Metal Bashing: Uher Miniline 220V Bucking Box
Our mains is quite high (at present 247V) and I noticed my Uher Miniline stack, marked 220V, was getting very hot in use.
The advice from Members here coalesced around a bucking transformer. After reading up on the Elliot Sound Products page on these, I wired a Velleman 209009C dual 9V transformer in ESP's recommended autotransformer configuration. It wasn't going to fit in the tight casings of the Miniline stack, so I took advantage of the relaxed Covid restrictions to get access to a workshop and some metal bashing advice from my brother, planning to make a case that matched the Uher aesthetic.
After calculating and drawing the folded net on a piece of filing cabinet panel, I snipped with shears and a Monodex nibbler, before filing to the scribed lines.
Lockdown has taught me basic welding, and I've made a bender to help put new sills on my car. This box was its first test. While a bit indelicate, I eventually got the folds in the right place, with only some areas that required soldering and filing back.
