I don't understand why PCB in picture??? I think that  layout format more preferred  .

А главное куда выложил - в файловый архив KMG. Видимо armkon по-совместительству еще и кул-хацкер ....

да не, он схему юзал ту что выложена кмг

А... Теперь понятно... Прочитал не внимательно...

have question about transformers back to back placing.
what two transformers will be best for this build?

230-12->10.5-230 = ~370V
but how many mA must have the 1 and the second transformer?
tubes will take 600mA
relays about 50mA
it will be ok if i use the first transformer: 230-12V 1A
and the second one: 230-10.5V 0.3A ??
i don't want to overload the second transformer  :-/

layouts for soldano (x88r lead / avenger preamp) and engl e530 version from KMG schematics that i make:

First of all U will overload 1st tansformer by 2nd. They must be inended for each other.
For not overloading the 2nd transformer - calculate the power it transforms in your case.

so how big in A must be the second transformer? i have 4A for 12V and 2A for 12V and 1,6A for 12V. I can use any of them?

[Marton]

ok
approx 250V * approx 6mA=1.5W approx = 2W

2W / 12V = 0.1666 A

i.e. 0.3 A is very good

so e530 DIY has 2 transformers??how big current??
