I "think" I am finished soldering my Paraset. It is always possible I missed something, but I hope not. Now it is time to make up the power supply and do the sheet metal work.

I made up a vintage dogbone resistor for my Paraset using an old one and inserting a standard colour coded resistor inside so that it had the correct resistance. Then I gave it the correct paint coding on the outside.
Did some soldering this weekend. Nearly finished soldering the Paraset together. Getting much closer. Finished making the receiver and transmitter coils. Made up some vintage looking capacitors. Just need to wax dip some of those. Then I can start wiring up the unit Finished preparing the front panel for my Paraset radio. Now I can start installing and soldering in components.
Made up a replacement knob for the RCA Victor control head I bought. This was kind of tricky since I have no idea what the original looked like (there are no pictures online), and the shaft had to fit into a square spline.
In 2010 I picked up a 1936 RCA Victor 5M automobile radio for $10. Unfortunately it did not come with a control head. A few weeks ago I came across one for sale on eBay, and was able to convince the owner to sell it separately from the radio. At some point, I would like to put this radio in my Model-A. It is missing a central knob, but I should be able to make up something suitable to match.
Some more progress on my Paraset. This time I machined up the Vernier knob for the slow motion control of the tuning dial.
Managed to get some work done on my Paraset radio today, Made some 1/4-inch shafts for the three condensers that are used in the radio. Also assembled the main tuning dial, and test fit them in the panel.
