DC issues using a Krell KSA 150 w/ tubed preamp?

Polyglot I am a tech and a Warranty Repair Station for ARC. The caps that failed in the C/J were C/J's own branded polystyrene caps. I'm sure they were not made by them. Their tech advised me that this series cap do indeed short and then heal themselves. Their update includes removing all those particular caps from the amp and replacing them with updated parts. I would contact C/J and ask them. My friend and great guy Ed who worked their for decades, retired and no longer works there in customer support. I don't know if you will be able to get any information from them.

Thanks Atmasphere and Hifigeek1 for your comments. I have/ had most of the CJ preamps starting from PV5 till the CT-5 and a bunch of SS and tube gear and only the CT-5 had this issue, in fact, that was the only one. Ed is indeed a very pleasant guy to speak to. Mel, who is taking over his job I believe, is very helpful.

Thanks Polyglot. I was unaware they hired someone new.
