Hello, I wanted to share for those interested the jump of the rotary selector of the 4333, I did everything so as to make the change reversible and not to transfigure the originality of the speaker, these selectors are very old and I assure you that you will get an improvement.
Here is the work.
To restore originality and biamblification just remove the blue jumps.
Jumper in the rotor towards you (11-12), (2-3), (5-6), (8-9)-------Jumper in the rotor towards the back of the diffuser (23-24), (21-20), (18-17)
These numbers correspond to the numbering on the crossover scheme 3133A, and you find them on the diagram that I previously posted
I've been living with this update for 10 days now, impressive improvement, bass more tense and deep, averages clearer, highs more extensive and defined, it may be necessary in some systems to slightly revise the L-Pad adjustments
