A wonderful little headphone amp that's really easy to listen to and takes up very little space. I'm including all the tubes I bought for it as they're no use to me without it but they were fun experimenting with (it was my first tube amp). My favourite combo is a GEC central tube and Mullard outputs, but the Philips are probably more accurate. It comes with the original Chinese tubes installed, which sound very different to the vintage ones.

The middle Philips tube may be nearing the end of its life (possibly, it sounded a bit odd the last time I used it) and the GEC I like most has a very faint hum with HD800, but they're still worth trying. The rest all worked perfectly the last time I used them, but once I found my best combo I just stuck with that.

Price is £400 cash on collection from Oxford (easy parking). I can also ship insured for £20, but the spare tubes are at buyers risk doing that. I have the original box for the amp itself and will pack the tubes as securely as possible.
