can you tell us what level of hum and buzz is at the speaker terminals when the RCA input is shorted with Rs=0r0.please take time to read previous post
Heii..Apex..I found problem on B500. Like this:
I used PSU +/-44VDC, If I not applied fuse, I measure voltase (+) and (-) to ground is simetris (44 vdc), also (+) and (-) to output power is simetris (44 vdc). But when I used fuse 10A, voltase (+) and (-) to ground not simetris, (+) to ground = 43vdc and (-) to ground only 35 vdc. Also (+) to out PA only 35vdc and (-) to out PA= 43 vdc.
If I used fuse 0,2A, voltase (+) to ground = 43vdc and (-) to ground = 42,3vdc. Also (+) to out PA=42,3vdc and (-) to out PA = 43vdc..
Please help me..

Use 10R resistors insted fuses and measure voltage drop on them, did you measure DC offset and voltages on other suggested points.

Thanks..I will try it..
hi sir how does the h900 works have you tried it already,,
