GMT King Cobra revived?

Nice work Dbanner

I reversed a.Tesoro Golden Sabre in the 90's and the pcb was marked Pantera. I don't remember the Pantera being marketed? But Tesoro had a tendency to recycle their circuits.The Golden Sabre was very popular.

GMT Cobra was a direct clone of the Golden Sabre promoted by Kellyco and the quality was inferior to Tesoro.

sharp eye of ivconic never sleeps - missed connection of this resistor!!!

What was the difference between the Pantera and Golden Sabre, external ground balance control?

Thanks for taking the trouble to share it.

update
the component on bottom left I do not know how it connects. It is not clear from the schematic diagram.

I put layout only for reference. Obviously not for making. It seems much the same as GMT king cobra.

i have the batch of pcb of GMT KING COBRA. 16 euro USD18 shipping included. no sharp need to redraw the pcb, you just waste your time at air.
had covered up tesoro-looking schematics on years ahead... no more reason to waste a time. just get-and-go project.
