Mainline -Voltage test

[bergurbrag]

Dear Mr. Brikeland

Can you please help me with the following:

I live in a country with 230 V AC. Iceland.
These are the numbers from page 88 from the Mainline manual
Can I use these numbers and if not what are the right ones ?

+275VDC on the Power Supply Board: 275V DC
+6.3vDC on the Power Supply Board : 55-65 V
-6.3vDC on the Power Supply Board: 50-60V
IA on the A side CAS Board : 275V
lA on the B side C4S Board: 275V
Breg Regulator Board (both sides): 220V
-reg Regulator Board (both sides) : 0V
Kreg Regulator Board (both sides) : 8-12V

Also Biasing from page 89:

Can use these numbers and if not then what are the right ones?

Leave the black probe attached to terminal 7. Read the voltage at terminal 20. Adjust the B side trim potentiometer until your meter reads 145VDC. Move your red probe to terminal 30. Adjust the A side trim potentiometer until your meter reads 145VDC

With Regards,

Bergur Bragason

If you set the power transformer for 230V AC (which is covered in the manual), then that accounts for the different mains voltage in your country.

Thank you !
I will post some other questions. Should I start another conversation or should I post it here?
