rockinrob86 said:I added mu metal around the output transformer, and it quieted down substantially. It was around -75db, and at that point izotope dehum takes care of the rest. I would build it with a different pt next time, or put that one in an outside enclosure.
What I should have been expecting, but was not, was how great this thing sounds with my ribbon mics. It should be obvious, they were made for each other and it sounds like it!
I’m probably going to build several of these. They’re cheap, easy to build and sound great!
Cool! Looks good.
Can you not move that PT to the outside? It'd be far quieter on the outside of the chassis.
5693 tubes: I consider mine, and any 1603/1620's scarce resources. They really only make a difference in the first stage, if at all, so I save mine for that position and use standard 6J7 / 6SJ7 in later slots. FWIW.
