Found my mistake: one of the 'new' input caps was damaged - thus the 12V DC output. Used a non-broken cap and everything is fine now, so thanks again Calamaro for your tutorial.

Does the DC offset do any good to sound quality?

Also, is it worth changing the pots? Will it do go to sound quality?

Default How can i make it more reliable?

Hi! Im a newb in this forum. I have been reading the comments nd reviews from you guys and i have decided to purchase 1. Im now a believer that the t2020 is one of the best! However, after a week of using it for some weird reason it just died.... I just hear clicking sound from both speakers. I have another one coming nextweek. What can i do to make this amp more reliable?

nice mods, I just bought this amp, I will try some mods!

First good thing, DC offset on mine is 10mV - 12 mV
While on my Sure Electronics TA2024 board, DC Offset was around 800mV !!

Fear SC59: yes lowering DC Offset could improve the sound but the main reason is that it could hurt the speaker
