Hi, i post my question here too
I have just finisched my ongaku and I am looking for good tensions. (pictures are on my thread “ongaku”)
I now 860V. But are the other values good?
For example to have –50V (-50 is the good value), It is not
–200V but – 155V.
Are 460 and +200 the good values?
Do you know the good value for the pin 1 of the 6072 and for pin 1 and 9 of the 5687?.
Thanks
Bruno
