Mike,  the Delta IIs were (are?)  notorious from having issues on the VCO 
boards.  I bought mine new and had to send it back a few times.  After the 
first Tentec did the repair work - no charge.  It seems that there were 
surface mounted gizmos and they had issues during production.

That exact problem 21 Mhz was the same one that I had.  so check those 
components on that board. (I say that but have never had the gumption to 
unpack those boards for a look-see.)
