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