How to replace National NC-300 tube ham receiver Filter capacitor

D-lab presents an economical filter cap replacement for the vintage National receivers. Yes, you can buy a drop in new manufactured type metal can cap for approx $45.00 or you can make a custom 3 section cap for about $5.00. The replacement cap is mounted on a 8 pin tube socket. Values are 2-47uf, 350vdc and 1-22uf, 400vdc, radial caps. I use adhesive lined heat shrink tube to adhere the workings together. I am offering this info as an option, not a requirement. The entire process takes about 1 hour to complete. 30 years from now, if this assy fails, the caps can be changed individual from topside. A nifty cheap solution!
