38-116 Code 121 Powering Up Help
#29

So since I am still have issues in reception, I thought it may be helpful to layout the changes I made in the power supply in case I screwed something up along the way. So coming into the radio the ac line cord hot lead goes directly into a new 2 amp slow blow fuse.  From there it goes to one leg of the on/off tone switch. The other leg of the on/off switch goes to an ungrounded pin on the a new terminal strip I added that is connected to a cL-90 inrush limiter (the CL-90 gets very hot by the way,  would burn my finger if I touched it more than a second) the other end of the CL-90 continues to take the hot back to the bakelite block (145) where it is connected to a primary from the transformer. Connected to this is a new .01 x1/y2 safety capacitor that is connected to the other primary from the transformer which is connected to the ac line cord neutral. The ground connection of the bakelite block 145 connects to the ground connection from the power transformer and the ground on pins 7 and 8 of the furthers left (from the bottom) 6L6 tube and connects to the ground connection of the aerial lead-in screw terminal on the back of the chassis. Attached is a photo of the above description:

Dan Double conversion is using two IF converters instead of one. This improves the image response. morzh — 07:15 PM
