Time to replace Tice Solo?

I have my pre, Bryston combo and VPI Classic 3 plugged into a Tice Solo power conditioner that has to be 30 yrs old. Is the Solo still a good unit or is it time to upgrade to a newer conditioner? By doing so, will I hear any sonic improvements? I'm on a tight budget; so, what conditioner will give me the most "bang for the buck"?
