I've done the build and i have strong dirty noises parasites in, unit off or on, around -30/-25 dbfs. Everything was good when testing exept with TR1 that i can't match the 1vAC, it only goes to 0,88v.

Have you got an idea what the first thing i've got to check?

Cheers.

Hi everyone, I have started building the 531T and there's three 470 condensers and one 470 KAK listed. I have four KAK. Is that an Issue?

Cheers.
