Barry, you're referring to C-551, right? That's the 2mfd/500V cap on the IF module. I have a few questions: 1. Is that a cap that frequently goes bad? 2. How do most people replace it? I have a 2 mfd/630V metalized polyester film cap. However, I'm not sure it will fit under the IF deck. As always, thanks for the help and guidance. Joe Connor
