Hello, Ed...
Let me know what the input impedance of your tube(s) are,
and I'll run my program that gives the values for C1 L1 and C2.
1000pf is fine for blocking, but you need 8500-10,000 pf for bypass
at the choke base on 160m. This is especially true if you are running
strings of electrolytics in the power supply.
