Help with Beveridge direct-drive amplifier oscillation

I have enjoyed a pair of 2SWs for about 5-6 years now. However, my pleasure is occasionally interrupted by prolonged periods of pain, as the direct-drive amplifiers unique to the Model 2 and 2SW are very prone to oscillate. A few years before he passed away, I had a phone conversation with Richard Modjeski (aka RAM) in which he talked about modifying the amplifiers in ways that he said made them much more stable. Unfortunately, I hesitated, and we lost RAM a few years ago. With him all knowledge of his modifications to the amplifier also seems to have vanished. Unless anyone here knows anything at all about it. I would greatly appreciate hearing from anyone who has any knowledge of RAM's Beveridge amplifier mods. Failing that, I would like to find a skilled person who understands the pitfalls of these amplifiers and has some experience and willingness to work on them. Thanks very much for any relevant information.
