There are 3. Part of the 34mhz AM and SSB oscillator cct. T6, T7,T8. T7 has no inner cap. The other 2 do. Sams doesnt show the values on the schematic and the parts list doesnt show any tuning coils. T7 Feeds T8. There are 2 tuning caps in that circuitry. These culprits are all located under the RF tin covers upfront. A fellow also told me about fake transistors. I knew that could be a possibility but had doubts because of my hfe findings. 150 is dang good gain for a final. How can they fake this? Anyhow, I do have a bunch if different known working ssb rigs that I can temporarily borrow the finals from. Before I do that I will test these possible fakes in the known good sets. If they drop in power well that answers part of the problem. Then I will move the good set to the 448 and see what happens. Stay tuned y'all!

73s!
