Re: [Amps] AL-1500 filter caps

["Carl" <km1h@jeremy.mv.com>]

Its more a repitition thing as those resistors have been a problem for ages 
as have the caps in the 3 top end models.
A certain person used to always say those caps were all specified and tested 
at 475V....yeah sure. Ive had to return several replacements that didnt even 
make it to 450.
