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

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.      

I did order a speaker protection board, T-type 30 amp relays. The power input says 10v- 16volt. I have found three different plug in transformers to power this unit. They are rated from 200ma, 1000ma, and one at 1800ma. which one should I use?

  What is the voltage of the transformer?
I think 200mA is a bit low, 1000mA and 1800mA should work.

The power input of the three transformers were 12 volt , with the 200ma ,1000ma, and 1800ma rating. should I look for for something bigger than that 1800ma?
