Philco 90 Restoration
#35

Another problem. I began the alignment. The IFs were almost right on, only the slightest improvement was made on one adjustment. The front end was a different story. I had the trimmers backed way out and still not peaked. That turned out to be a mechanical problem, I had not indexed the dial properly. That was easily fixed. But still, I couldn't get the thing to track. After looking for a while and some head scratching, it hit me. The trimmers on the tuning condenser have two different size adjustable plates, the one for the oscillator section is smaller than the other two. When I assembled the tuning condenser, I had it in my head, the front section was the oscillator, while actually the most rear one is the oscillator. The bad thing about this is, you can't get to the screws so, I had to remove the condenser to correct this problem. After everything was back together as it should be, the radio aligned perfectly. Even after "rocking" the bottom end, the dial is almost right on.

The radio has been playing for several hours now. The only problem I see is the dial light flickers and sometimes goes out and the volume control is a little scratchy. I still have to paint the tube shields and I have that speaker problem to deal with.
