AK808A
#50

Another piece of good news, the shadograph works. It does have a resistor in parallel inside it, but 1K kinda gave me hope the coil was intact.
I had to swap the lights places, the dial one was very bright whereas the shaograph was on the dim side, so after that the shadograph became really crisp, just had to adjust the lamp hoder position.

The sensitivity is so far so-so which might be due to antenna absense, or Avc Voltage not developed proprely, will look at it.

I also thought of magnet being weak but then in the beginning it forms very thin line, and then goes almost full width, after which it settles in the middle and does react to tuning but not as much as I'd like, this is why I think the magnet is fine.

My bet is on antenna as the 2nd detector (I have yet to see where it goes to the meter but has to be it) tube is very strong.
