Everything is included, PSU, valves, instructions, the works. I'm asking £50 delivered to your door. Probably cost around £100 to get imported from Japan.

Free bump and some hopefully helpful feedback...

I have one of these hooked up to two ZA3 amps and a ZD3 DAC

Whilst this P3 is also a preamp, I am using it as a desktop headphone amplifier

Really happy with it and intend buying upgraded tubes at some point.

Still available! Entry level pre-amp for those wanting to try some valve rolling. I'm open to offers, this would make an excellent alternative pre-amp in a second system, or maybe you want to try out some of the new chineese gear that's continually reviewed on you tube.

I see that one of the alternative valves that can be used in this is the 6J1. I bought a cheapo 6J1 pre-amp which was the subject of several mods on Diyaudio. After all the mods it sounded great for the pennies spent. Fosi stuff is really gaining ground. GLWS.

Andy not sure if your aware but across on Maverick Forum they have a Fosi owners club, the brand is causing a bit of interest over there, so it may be worth putting your advert up over there, I have posted that you have this available on AOS.

Hi Andrew, is this still available? I have no idea what I would do with it, but for some reason it keeps playing on my mind - probably because I've never owned a tube anything, and it would be fun to play with! :)

It only took me 9 weeks to decide that yes, I would have this! Some times I think I'm indecisive, but now I'm not so sure!

Arrived today (thanks Andrew) and had a little time to have a play tonight - It's going to be used as a desktop headphone amp mainly, and so far I'm quite impressed - I had expected it to be smooth due to the valves but it's quite forward in presentation on first couple of listens. It's certainly an improvement on direct out of my iPad headphone socket so that's a good start, and the build quality for such a cheap item is superb - the volume and tone control pots feel quality, as is the toggle switch for power/source selection. Very happy so far.
