"813s don't need a VHF suppressor because they are pushing the limit
at 28MHz."

On the contrary, I remember seeing a single 813 amp for 50Mhz in a handbook 
somewhere. Also, my problem was spur generation in the VHF region. Now 
whether other components were involved with this, I don't know. I do know 
that the spurs were eliminated after the nichrome suppressors were 
installed.
