You mean load at the heater and B+ section at the output with 3 resistors to adjust the trimpot....????

If the voltage slightly exceed to 270v+/-30v after adjusting the R1, R2 & R3 value would this be a no no...???
My mistake...perhaps this is the right way to load the heater to adjust the voltage to 6.3V....3 resistors in series....please correct me if i'm wrong...

Yes, I replaced R11 with 680r and R8/R9 with 1r. Then there where no problem adjusting to 6.3V...

I haven't still managed to get full voltage from the HV section. I have followed the steps suggested in this thread and got aprox. 260V. As soon as possible I will try and fiddle some more with it.

Hi,
I would also delete LM338 from schematic to avoid complications and leave LT1084 or LT1085 so you have only to play with R8 and R9

Hi quanghao,
thanks for schematics and part list, but, can you write on schematics its revision or date ?
There are a lot of schematics on the web, and there is a little bit confusion find the last
one.
Thanks
Ivano
