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.
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.

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! |
Some user install speaker protection module in
model 400
to protect their speakers http://www.ebay.com/itm/UPC1237-Dual-Channel-Speaker-Protection-Circuit-Board-Boot-Mute-Delay-DC-12-... |
I did look at that speaker protection module on ebay, there are a few, what size would I need. What would be the best choice? I have never even seen any of of these, I will get whatever one needed to protect my speakers whatever the cost. How does it get hooked up, just hook it up in line from the amp to the speakers like you would a fuse. |
Now addressing the issue about using a Variac to power up this amp and preamp. how big of a unit do I need, I did look on amazon and saw lots of them, but have no Idea what I should use. And really don't want to spend a lot of money on something I probably use this one time. Any suggestions on how I can do this, without the Variac,or is this the only reasonable way to save this amp. |
