[Heath] SB-110A ? SOLVED

[G3OOU at aol.com]

Hi Ken
 
According to my (poor quality) SB-102 circuit the diode on the molex  
shorting plug goes between pins 3 (anode) and 8 (cathode) and appears to be in  
series with the screen supply. With the external transverter connected, the  
screen supply should be controlled by a switch or relay in the transverter  
to allow convenient switching between HF and VHF.
