I still have over 100 plastic housings for the King Cobra, some face plates without decal, battery doors and some 60 complete rods left if anyone is interested. Keith Wills

Do you have a photo of the plastic housings?

[kt315]

Keith does not answer. I can do the photos from my original one.

Jürgen, Thank you lots for the support of my work.

I got a response with invoice. Second batch will be 20pcs. They added yet 10pcs like a bonus I asked them of, so it gives me some reserve on abatement of the cost.

how to connect those points: NF , PA, 1 , 2, 3, 4 and GND writing in your drawing?

- PA - test point; for o-scope connect at testing - measuring of RX phase and amplitude.
- AM and NF - test points; for future connections with VDI board.
- +8V, -8V, GND - for connections with VDI board, power supply lines for VDI board, for future.
- 1 2 3 4 - same as in the original, besause the PCB is due copy and I have to make that I see. may be for future mod, look my post #51 and answers ## 52. 53, 55
