SVS-PC13 Ultra Bash amp low dc volts?

[moss99]

Hi all , I have a SVS-PC13 u tube sub with a Bash amp , it powers on fine and works with the test tone but at a very low volume output , the dc output is only 10.5 Vdc , does this sound low ? and would that cause the low output .

Update , I guess the 10.5 vdc is correct , (it seemed low compared to other amps i have worked on) ,
I found a bad joint on resistor 103 and a 100 uf cap (C203) was bad too (see pics) . It is working fine again now ..
