As for the CD player, it should say what the output is in the manual.

I built Aikido preamp with 6n2p's for my PA150 and it's a great combination. The warm tube sound pairs nicely with PA150's transparency and power. A lot of gain (use 6n1p or 6n6p for lower gain), but I love it.

where is a good place to purchase an aikido preamp kit?

and i am using my old sony playstation as a CD player, any idea what the output characteristics of a PS-1 is?

I got mine from tubecad.com

can you tell me which one in particular, there are apparently alot of "aikido" preamps, more over there are a crapton of options when going to order it

After doing a bit of research, it sounds like a preamp would help you. The PS1 apparently has a 1.09V RMS output, which is much lower than the 2V that is common with CD players. A gain of 2 would get you pretty close to where you want to be.

I have some ESP P88 kits. They have a switch for setting different gain levels.

ESP P05b and P88b Kits up for grabs

@col that looks pretty cool, what can you tell me about this preamp as a solution for my gainclone / how "hifi" are the components (namely the opamps) used?

I got the PS-1 power supply, but it's out of stock, so the PS-3 would work in its place. And then I got the "Aikido 9-Pin Stereo PCB" and ordered my own parts. But in retrospect, you can just get all the parts and the upgraded cap option from tubecad and be done with it.

I would order some 6N1P-EV, 6N2P-EV and 6N6P from ebay and experiment. They are about a buck each, and I settled on 6N2P.

I also got a nice case from diyclub.biz and their remote control kit.

The PA150 is incredible sounding, I love the raw power and clarity, not a hint of harshness. Hope you are enjoying it as much as I am.
