Need to find help for repair of IRS Beta X-over

One channel of x-over seems to be intermittent.
Thanks for your help.
I've had two RS1b active x-overs repaired by Rick Rupert of Ruperts Music in PA. He did a great job and is very reasonable. His email is: Tel: 570-323-2911 Drop him a line and he will let you know if he can do it or not.
