UPDATE

Powered up to do Alignment, NO RF !!!!!!!!!

Went to check OSC Tube Voltages. Touched my Meter probe to Plate Pin 2
RF returned. So osc was not running

Cleaned tube pins and cleaned pins and socket with contact cleaner.

Came back 2 hours later. Aligned IF , went very well. Peaked nice @ 260KC

Went to to rf alignment , rf disappeared again. Once again touched Pin 2 of OSC and rf came back.

This time I re soldered the connector pin 2 and bent the contact points closed.

Completed rf alignment , again all went well.

If I loose rf again will try another 24A Tube. I do not see any bad connections in the area.

Time will tell

Meanwhile enjoying 40's Hit via my SSTRAN Icon_clap
