You need to quit making a new thread every time you work on a different part of this amp....if it is the same amp. We have to go through a lot of questions about what has been done to it before. Is this the one that has high DC offset on the speaker outputs? Is this the one you are having driver board problems with?

Are these measurements with the dim bulb in circuit? 2.512 what?

 

[changdangnz]

Yes , it is. I was doing test under DBT.

Lee , this is a series 2 version just pick up from garage sale. I had been blow fuse and 1 channel output dead. I just recap and test all transistor and output transistor. I had replace all new output transistor. Only issue is power short .

I am still waiting for a bias pot adjustment to finish my pl400 series 1. Not far to bring sound back.

Is the bulb dim or bright? Are you measuring DC or ac,?

 

[changdangnz]

The bulb is bright and i measure on dc.

I try measure on AC bridge rectifier again and give me a value is 3.66 v

Pull the 5 amp rail fuses and see if the bulb dims.....

What were in there for outputs? Was it a fully comp Ser II?

 

[changdangnz]

1 channels is original output tp9054 set and 1 chanels is xpl910.

Pull the 5 amp fuses and try it again...

Lee. I had removed all 5a fuse and the bulb is still bright
