sorry to dig up such an old thread! but i have transformer hum and am planning to implement the dc blocker tonight. i intend to use 4 1n4004 (1a 400v) diodes and 4 2200uF 16v electrolytic caps in a similar manner to this, however i will parallel 2 caps to get 4400uF on each half (since i couldn't find the 3300/4700uF sizes) and i will be using 2 diodes in series in place of each one on the original diagram.
questions:
1) is this safe?
2) is there a better option to fix transformer hum? my humming problem has been narrowed down to the proximity between the transformer (toroidal type btw) and my amp circuit boards.
