Update:
Received the new HP 1820-0119 IC today and couldn't wait to solder the new chip into the 5216A.
I ended up buying 2 chips on eBay for 17 dollars. Yikes!
They were HP stamped but not gold plated as are the rest of the chips.
Now all tubes are working properly and also all Frequency and Sensitivity knob positions.
Measuring 10Mhz from the back of my new ovenized 5335A shows 10.00002 / 10.00003 pretty good!
