Thanks Mike. 
I indicated earlier this 610 was unmolested, but that was more a commentary on it's cabinet than it's electronics.  I knew it had already had a filter change . They still have to go again...looks like at least one of them is leaking and I don't think they're the correct values.  I'd really like to get the poor 39-6 C I going before I tackle this dude.
