Door noob question (again..). I’m trying to find these lams. but no luck so far. What kind of transformer was this? As in what type..It's a nice build indeed. Regarding the front panel, I wouldn't change a thing - looks great
Here's a quick tip to reduce hum induced by internal power transformers:
These are the lams of a 300W power transformer from an old halogen string light that I 'reverse-engineered' a few years ago. The lams are similar to the transformer shields you can buy at e.g. Don Audio. Those work fine but are insanely overpriced IMHO.
I just wrap two or three layers of these lams around my internal power transformer and secure it with electrical tape. Both of my TG units have it as well. Here it is in a 6-channel mic pre that I designed:
Place the transformer as far as possible from audio circuitry, wrap the lams around it and rotate till the hum is gone. HTH
