Default Please Help: CDP Primaluna P8 for repair

I have a Primaluna P8 which is not working. In the past few weeks, the problem is on and off (i mean sometimes it's working then the next day it will not).
There is no music in the analog output (both channel), it is only a hzzzzzz..... but the digital output is working fine. I tried changing the output tubes (2pcs. 12au7 and 2 pcs. 12ax7) but still the same problem.

I'd checked the voltages in all the volage regulators but they were fine.

Please help.......

Easy to locate the fault if you have at least a scope.

that is one of my broblem, co'z i don't have a scope.

There are 4pcs. of NE5534 after the DAC. I think that this op-amps are OK because i don't think that they will get damage at one time, both channel is stop working at the same time and the supply voltage for this op-amp were fine..
Could it be the DAC?
The hzzzz.. is the same volume level in my speaker when CDP is still working. The only diffrence now is no music only the hzzzzz..
