275V test.

Reads 366V

What to do?

[Paul Birkeland]

What AC line voltage did you measure and how did you wire your power transformer primary?

[Tabaia]

What AC line voltage initially measured between 230 and 247
I used the wiring for Greater than 235V and Less than 245V.

Also Reading the manual and getting my head around this i realise that the reading I have for the board 235V is probably OK.
Manual says it should read between 300-500VDC , mine reads 366VDC.
I assume that is fine?

[Paul Birkeland]

Yes, all is well.   The voltage at that node will be relatively high when there's nothing built in the amp to load it down.

Great !Im on track.
Thank you.

Hello,
I have finally come to the point of checking the Ohm's
Here are my current issues:
Mostly where it say 0 - my multimeter reads Ohm
And on terminals 19 & 22 i get a reading of 200Ohm's.

What could be the issue?

Looking forward to your response.
 

[Paul Birkeland]

Could you post some pictures of these readings as they appear on the meter?

[Tabaia]

Here are the readings of terminals 19 and 22

[Paul Birkeland]

That's 200K, which is 200,000 ohms.

[Tabaia]

Ok thanks Paul.
Are those readings ok for those terminals?
The m,anual says otherwise.

[Paul Birkeland]

Ok thanks Paul.
Are those readings ok for those terminals?
The m,anual says otherwise.

For which terminals? 

[Tabaia]

Terminals 19 and 22

[Paul Birkeland]

You have 200K at terminals 19 and 22, which is consistent with what's written in the manual.

Hello again,
Just wanted to run my tests by you.
Here is a completed list of all the terminal tests.
It seems that the terminals that have no connection and no grounding all read zero.
Kindly have a look and let me know if there are any issues.
Many thanks

Could you double check terminal 20?
