---------------------- multipart/alternative attachment Hi Aaron, I'm with the other guys on not enough jack clearance causing the bobbling. But in answer to your question about parts, give Schaff a call. I know they aren't in the catalogue, BUT, when M&H had one of their clearing houses in the 80's, I believe it was Tuners Supply that bought up a bunch of their old parts. Now that Schaff owns what's left of that, there just could be some laying around somewhere, never know. But unless the hammers are just flopping around from side to side, I really don't think that's the problem with bobbling.
