1. Peaked the second IF. Total peaking makes it oscillate so have to get a bit off-peak, and ended up on both IFs pretty much where they were before.
2. Opened the volume pot. It is the same type as was in my Philco 111, where the rotor has a cam that presses aganst a circular metal band inside the circular resistive element. Trouble with those, the cam rubs against the band and either way it is a forward pushing action so it enounters lots of friction. I added some lithium grease and it became much better. Plus some deoxit for the resistor itself.
It has to be not used much, the value did not go away much at all.
3. The SW 5.5-17Mhz band is accurate enough, and so is BC band. Conidering the pointer has to be screwed tight and the dial itself can be rotated inside the frame.
The Police band (2-5Mhz) is less acurate. I guess this is the coil on the blue bobbin I had to fully recreate. Then again, who needs that one. It is about 0.1Mhz off on some part of the scale, much better towards lower end and 0.2MHz off at higher end. Screw it. There are no stations there anyway (yesterday I got one...so do I get on my other radios with the Police band).
Not a bad guess though.....

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
