Ian, Have you tried checking the small toroid RF Chokes for shorts to the crystal can? That is a common cause of the problem you describe. Just stick a small piece of paper between the chokes and the crystal cans for a quick check - if the receiver comes to life, rewind the chokes (being careful not to scrape the wire insulation).
You can ignore the voltage at U4-3 until after you have properly adjusted the carrier balance - that voltage depends on the exact setting of the balance pot. 73, Don W3FPR > -----Original Message----- > > Hi all, > Well I have finally started looking for the fault on my SSB board after > about 9 months!
