Suggestions for testing a never installed, 20-year boxed amp.

Thanks. I appreciate your advice. 

All good ideas. I'll try to contact Pass Labs Monday before doing anything. I already have a lightbulb current limiter setup, a variac, and some 250W 8ohm resistors.

My acquisition of this amp is a long story. The company I worked for, at the time, set up a number of QC stations and 3rd eye approval stations for mastering DVD movies for major studios. This amp was never used in any of the setups. It sat in the shop for years until the US operation was closed. I purchased this and some other equipment from the company before moving on. My plan was to set up a better home theater system with this amp. I also purchased a new Marantz AV7005 that's also still in its box. Basically, I couldn't find speakers that my wife could live with. Now I'm trying to decide what I should do with these items.

I'll let you know what Pass Labs tells me. Thanks again!

OK - I took your advice and contacted Pass Labs. Someone actually answered the phone and referred me to Kent who was very helpful. His concern was with the capacitors as some of you mentioned. Kent recommended a "current limited power up" using a 120vac current limited power supply. I asked if a light-bulb limiting circuit would be Ok and he said to cook the amp for a day with a 60w bulb then move up to a higher wattage bulb for another day. Of course, he cautioned me about safety concerns. No connections to inputs or outputs are necessary. 

Kent offered to do this for me if I wanted to ship it to them for a nominal fee. He said he could also re-cap the amp if it becomes necessary. He also offered to send me instructions to make the speaker connectors banana plug ready. 

I don't have any decent speakers for this amp. If this amp tests ok I will have a tough decision to make. Do I keep it and build a system around it or get rid of it? Either way, I need to know if it works.
