Mile hello! Build H900 to work without limiting the 3600w 2ohms and made the following modifications:
1k resistor R15-R16 680R to ally overwritten with VAS.
6 IRF2807 mosfets used in + ve 6 mosfets irf2807 in-v.
I used 16 and 16 2SA1943 2SC5200 the outputs.
overwritten by resistor 0R33 -> 0R47
4 x 100v capacitor 12000UF
Trafo 40 40 0 ​​40 40 - 4,5 KVA got 2000w without distortion. Above distorts a lot.
I want to put trafo 50 50 0 50 50 for 3600wrms. What modifications made?
The vertex with 16 pairs of works 5000wrms 5200 1943 at 2 ohms? The scheme works provided that Mr.? Thank mile.
