The Bottlehead Kaiju 300B amplifier was mentioned by another member. If you want to get into DIY tubes, the Bottlehead kits are a great way to go. The instructions are fabulously easy to understand and follow, and help is always available via a superb online forum. Most importantly, what you end up with is a high quality amp with excellent sonic performance. You get point-to-point wiring in the signal path, and the component quality is excellent. The Kaiju is a great 8 watt stereo amp that can be monoblocked into 16 watts per channel. I am currently running my Kaiju in stereo but hope to ultimately purchase another Kaiju kit to run as monoblocks. I have also fallen in love with the DIY process. Building your own amps is great fun, and nothing beats listening to gear that you have built yourself. I can heartily recommend the Bottlehead kits in general, and the Kaiju 300B kit in particular.
