Problem resolved. After going back over the wiring I was sure that the shield of the 7A8 had to go to the chassis and sure enough it was thru the cap/coil combo that I decided to leave out. I only replaced the capacitor but no connection thru the deleted coil to the chassis.
Also found that the 250 pfd mica cap #32 was not in its proper place. It was connected on the 35A5 tube between pins 6 and 7. Thats how I found it originally. Once I removed it I decided to check its value and it was 1/10 of what it should have been. Read 25 pfd even though the color code was red,green, brown. Not having a 250 cap I paralled 2 120pfd silver micas and placed it between pins 2 and 7 of the 7C6 and restarted the alignment.
Although the loudness of the tone was not that great using the AVC voltage to set the alignment worked out just fine. I now have a playing 40-220. Now all thats left is to replace the yellowed and partially shrunken dial lens.
