Practical Photos for P.A. on Tube GU-43B

 

 

Photo # 9

 

Photo # 9. Here is PCB for PA. It is possible to use A PCB of any reasonable sizes. Dot in the center is place for heater of the tube. Four Dashes are places for soldering of the cathode tube. Three dots round the dashes are for holes for holders for screen greed. The holes should be insulated from the ground.

 

Photo # 10. Heater and Cathode of the tube is already soldered at their places. There were soldered with help of a small Gas Burner HT- 950 (it is shown at the left upper corner).
