John, Even a "software guy" may be able to read a schematic - at least to the extent that it shows 'which is connected to what'. Do check the schematic and you should see that the only thing between RFC5 and the collector of Q6 is T3. Check that toroid carefully for poorly tinned and soldered leads. If you can see any enamel on the solder side of the board, that is a sure sign that the lead was not well stripped and tinned. Removal and re-tinning is the only cure.
