Just ran into this topic. Thanks for sharing.
I have a Titan 5ch myself, since 2002. It’s about the only thing that I haven’t replaced in 20+ yrs. I love this amp. It’s good to know that Simaudio is still supporting legacy products. After reading this, I just might send my Titan in for some maintenance. I just have to process the wait time. I also don’t have the shopping carton anymore. Under a month would be fine but I wouldn’t know what to do with myself if it was longer.
