What's wrong with my rackmount effect box?

My Digitech Studio Quad 1u rackmount box gets unhappy over time (hours). As it warms up, the input levels drop and it becomes unusable. Turned off for a few hours, it comes back to life. Is this terminal or repairable? Should I get something new? Is there a comparable product (multiple ins/outs, flexible routing)?
I have a Digitech Studio Quad
, 4 in 4 out rackmount unit. Purchased new approx 15 years ago. Has been in storage for 10 of those 15 years. It is connected via send/return to a Mackie 1402 mixer.
It works perfectly for a few hours when turned on cold. Once warmed up the inputs go silent unless given a very high volume signal which seems to 'shock' the gain back to the correct stage. When use continues, the input levels will slowly drop until shocked open again. Some other glitching occurs but may be because of overload inputs.
Is there an explanation for this behavior? Is it repairable? Am I using incorrect cabling/gain staging?
