Hello All,
In the process to adjust the bias around (100mV) as per Mr. Nelson Pass recommandation, I cannot go below 600mv! is it because I am using TO3 Exicon 10N20 and 10P20?. The bias transistor fixed on the heatsink is a BD139 instead of a MPSL.
It is really hot (i cannot leave my finger on the heatsink more than 4-5 sec but the bandwith is huge on the scope and the sound is great on my JBL 100 Century.
Many thanks,
jp
