Smile Is this top of bottom view of 12AX7 / 6N30P?

Reality check before I burn stuff: Is this top of socket view or bottom of socket view for these tubes?

Thanks so much

Petter

Hi Petter.Glad to hear from you.
I think I remembered an old rule for tubes that the 1 was first left view from bottom.Don't know if it makes clear or not, but...I am not so tubed

I think you could see the filaments at the center of the tube,should be 4 5 with 6.3V

Sometimes the common is not specified to inside tube for a 12V operation

OUUUPPSS ! irate:

Hope you won't burn anything....

Default 12ax7

Check continuity across 3 and 4.

I think you are looking down from top of tube therefore top view.

Count clockwise when you're soldering it. That does it for me

The diagram you drew in your post is wrong. Looking from underneath, it is the opposite.
