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

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.

So will 1.0 amp or 1.5 amp be to big.

Either is fine to supply power to the protection module.

I should not have to do this for the preamp, correct?

I recommend using the bulb tester to power up the preamp too, just use a 25W light bulb for an hour.

BTW, connect a pair of cheap speakers for testing before you install the protection module.

Well I did do all them things with the bulb tester to the main amp, did the same with the  preamp,hooked up the unit, used some cheap speakers and everything actually worked. Only issue was I had to use the rear outputs on the preamp to the main amp inputs, I originally had them hooked up to the front outputs, and the unit sent no signal to the speakers. I don't know why, but it works this way so I will leave well enough alone. I do have the speaker module ordered and will use the cheap speakers until it gets here. I would like to thank everyone who offered any suggestions to help get this unit going. I have had it for a long time and sure did not want to burn it up. I really do appreciate all your words of wisdom! Thank you DRW.
