1958 Handbook, chapter 6 (HF Transmitters) p. 164:  Subsection entitled 
"VHF Parasitic Oscillation" specifically addresses this.  It's too much 
to type and I don't have a scanner, but it describes how to check for 
VHF parasitics, how to determine the frequency, and how to suppress them.

This appears in a section called "Stabilizing Amplifiers", which 
separately discusses LF, HF and VHF self-oscillation, causes and cures.
