Post subject: Heathkit SB product detector issues. Posted: May am. Member: Joined: Nov am Posts: Location: Albany, NY The voltages at pin 5, pin 7 and pin 10 differ from what the manual says is correct. At pin 5 the voltage in LSB, USB and CW is correct at about 47vdc but the voltage does not.
here is my recently acquired and restored Heathkit SB SWL receiver. It is a fairly unique item, much less common that the SB// receivers. I don't have the full manual with the voltage chart, can you post a scan of that chart because it doesn't make sense given the schematic of the SB The SB schematic I show has pin 10 as the plate of the product detector and it is fed with a K directly off the filtered B+ so it won't change much with mode and the voltage you measured. Heathkit SB SPECIFICATIONS. GENERAL: Type: HF receiver: Frequency range: MHz in 9 bands MHz MHz MHz MHz MHz
