| Yes, the layout kind of not optimum. You might try to lay the transformers sidewise and to make the RCA atop, above the transformers. Still, I hope you understand that your hum has very little to do with layout. Properly grounded unit shell has no noise in open incisures. You need to play with grounds. I usually use by-pass ground techniques – never failed on me. One you find a proper grounding then whatever you will do with the corrector will produce no noise. BTW, I did ask anybody to mane the uploaded images identifiable, so please…. |
