I think your right. I don't have the right schematic. The one I'm looking at is for the model 25A. They're similar but not exact. I removed the black tape and took a few pictures. Guess I'll have to see if I can get the right schematic or draw out the entire chassis. My set has the optional powering plug in the back. Knowing that what I thought was and output transformer is a choke I think the two blue caps are the C9 caps shown on the 25A schematic only the C9 caps on the 25A schematic are 4mf and the ones in my set are 8mf.
Are you saying the Mite cap is the C6 cap on the 25A schematic or is it not shown on the 25A schematic? Or is it C7 on the 25A schematic? If it's C7 on the 25A schematic then I'm sure we can't use the 25A schematic as the 25A schematic shows one leg of the C7 going to the cathode of 37tube and the other going to the other side of the line input where as on my chassis the one end does go to the cathode of the 37 tube but the other end was going to be grounded to the chassis. It's hard for me to know if the previous restorer was redesigning the circuit or if the original component was attached to ground and they were just replacing what they had originally. The Mite is not and original component is it?
What was under the friction tape is the upper most red component in the top down photo it has the end painted green. Is that an original component? I don't know what it is. The long red component with the green dot below the Green end component is a mystery too. Don't think that was original either.
To add to the fun the red long cylindrical component with the green end has both lead soldered to the ground bar extension from one of the pins on the 38 tube.
The 38 tube has 6 possible connections to it none of which on the 25A schematic are tied directly to ground. The ground bar that is coming off of one of the tube pins on the 38 tube on my set is definitely going to ground. As none of the pins are numbered on the schematic it's a little hard to tell which pin is which.
Nice little radio hope I can get it working again.
Thanks for the feedback
