the mje 340 (Q5) must be in the same heatshink with final transistor, better if the mje 15032-33 on the same heatshink also
I wanted to ask Mr.Mile or the other could answer, even fellow DIYer may experience the same thing with this problem, .. why the H900 standard when playing a kick drum, bass disappears (PA as SUB) ... the 4R or 8R load. but if for a bass guitar no problem, voltage regulator 45ac-90ac-ct ... 4kva. and I do not use nsl 32. where is that must be repaired or is there any other damage?
sorry my bad english
thanks and regards

Done checking componet and voltage measuring found out 100r resistor change value to 1mr and finally my b500 is working fine now thanks to mr.apex and to other here.
Its sound really good 🙂
