�  It may be hard to get an answer, Jon.  During the grate parasitics 
debate, I asked Tom Rauch at least seven times whether or not the AL-1500 
used a VHF parasitic-suppressor, and he stonewalled me.  //  During the 
debate, a (shy) reader ran the 8877 on a computer app. for amplifier 
design he used at work. He told me that the 8877 is capable of 
oscillating above 100MHz due to the amount of feedback-C and gain.
