Simple Question (McTube Power Supply)

[blindsjc]

Hi friends,
Just to be sure: Can I ignore one of diodes D5 or D6
to get 6V from this mctube power supply schematic?



Do you think this will affect the rest of power supply
or it can work ok this way? I will use 6N2P tubes and
need 6V filament. Thanks.

The easiest way I can think to do it would be to connect the filaments of the two tubes in series. This way they will work with 12v and no changes will need to be made to the supply.

The effect use just one tube,
I will test it today, maybe a voltage divider
can make better work. Thanks friend.

I made a voltage divider and get 6.5V from the power supply schematic above, but my
tubes filament dont work. Used another supply just for filaments and they work, and the
effect too. What's going on??? 6n2p are just russian 12ax7 with 6V filament...the supply
appears do not serve the power (A) they need.

Some idea? Maybe a voltage divider problem?
Maybe the transformers? but they are 12V 0.5A
as schematic...
