I don't want to say that I am denying that Tom may have changed his 
story.  So, let me ask the question.  Maybe we can get to the truth:

Tom:  Did you say that you have seen parasitic oscillation damage of 
*ANY* kind in SB-220s?

The reason is that while Tom may have never seen *VHF* oscillation 
damage, he may have seen damage due to oscillations at *HF*.  HF 
parasitic oscillations can occur in an amp that is not properly 
neutralized.  Especially the two tube variety.

So Tom, please clarify for all of us what you told Rich.

Rich:  In your conversation with Tom, did he *SPECIFICALLY* say that the 
damage was due to VHF oscillations or oscillations in general?

Just interested in the truth.

73,
