How to conserve huge cash on multi section radio filter capacitors. A common chassis mount multi section cap will run you regarding $50.00 shipped. You can construct this set on your own for $10.00. The octal base can support any kind of value plan you pick. Radial caps are easily offered. I utilize this approach for many Ham/Shortwave radios as well as smaller tube amplifiers. Excellent service and enjoyable to construct. I have Drake R4 and 2B series on hand.
