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

Any suggestions on how I can do this, without the Variac

If you DIY, a 100W incandescent light bulb will work well in this case:

If you aren't experienced with wiring, or those diagram looks confusing, get assistance from someone more experienced.

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.

In the picture of the link show the connections, you also need a 12vdc adapter to power the module.

Is this the one that I should get? In the above mentioned site. The owner's manual says the amp is 200 watt per channel,I believe. So this module will be big enough?   And yes I see the 12 volt connection for the transformer. That will be no problem to get.  

And this light bulb tester will work to charge the capacitors, so I should not need to buy a Variac for this one time use?  

Is this the one that I should get?

Yes, or bigger relays but not smaller

And this light bulb tester will work to charge the capacitors, so I should not need to buy a Variac for this one time use?

Yes, you can start with a 15w incandescent light bulb for about 12-24 hrs, then use a 40w bulb for another 12-24 hrs to reform the capacitors, then follow by a 100w bulb for an hour to make sure the amplifier still working fine.

Ok first, I will get that module, that sounds like a realistic item to save my speakers. And I did read through that post on that site about that light bulb tester. And for the most part the assembly sound pretty basic. I don't  think I should have any problems putting that together. And then I will recharge the capacitors as you instructed. It may take me a few days to put that light fixture together, but I will let you know how things are going as they progress. Thank you for the positive feedback, at least now I have a direction which to go. I do appreciate all your help, Again thank you. DRW.
