Hooking up my phase linear model 2000 preamp, to my model 400 main amp.

I had these two units for years,hooked them up back in 2001,found they needed some work, had them repaired they have sat in the shipping box ever since. I did hook then up years ago but don't remember how I did it. Now I have them again, and want to get them going . And don't want to burn something up hooking them up wrong. Can someone give me some direction how to do this. Thanks DRW.

Connect a pair of cheap speakers for testing just in case....

be carefull about that 400 amp. it's known to fry speakers with 'dc' current!

I did finally find an owners manual And it even said one should put an inline fuse in the loop, to prevent that from happening. They recommend a 1, 11/2, to a 2 amp. any thoughts about this. I just don't want to put heavy of a fuse and have the current walk through it. I do appreciate the words of wisdom, I never thought that could happen. And I am running a pair of JBL LX 55 's, and a pair of infinity IL 40's. so yes I don't want anything to happen to either of them. again thank you.

Since they haven't been turned-on in years I recommend using a VARIAC to slowly bring up the AC voltage (over,say, a 12 hour period) to avoid stressing the power supply caps in both the pre and power amp. And yes, the 400 does have a reputation for troublesome behavior - I have one myself (though not in present use). Good luck!
