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

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?

300mA is adequate.

Well I did get that light bulb tester made. It was really quite easy. I hooked it up to the amp,turned it on,used a 25 watt light bulb only put out  49 ac volts, ran it for 10 -12 hours.The second bulb was 65 watts, it put out 93 volts, will let it run for 12 hours.Then will run a 100 watt bulb like you said for an hour. then power up the amp on it's own. Hopefully everything will work out good. Then I should be all set, just have to wait for the speaker module, I did pick up two,12 volt transformers. One 1.0 amp the other 1.5 amp. I hope these will be big enough to power that module. I will keep you posted about how this goes, probably will fire both units tomorrow. I should not have to do this for the preamp, correct?     

So will 1.0 amp or 1.5 amp be to big.
