Welcome to the Carver Site.
Searching for the words "mxr 130"" or "mxr130" will bring up more pages of information that are sure to help you on your unit's journey to recovery.
This is just one of many posts on the 130. One vender is mentioned in this post (Circuits and Concepts) and he has parts for the 130. You can find him on eBay
In that very same post, you will find this comment.
"The MXR130 issues are pretty well documented and most fixes simple. Yes, all older gear should get capacitors, etc, but I would gamble that a well maintained 130 or 150 will last longer than what's generally available in retail box stores today. Sound great, too! No need to fear keeping one going!"
And as @3M_Audio mentioned, "what exactly is going on with your unit and what parts are you looking for? "
Enjoy your stay here.
