Over at DiyAudioProjects Mark Houston has given his impressions on the Jan6418 Valve Pre-amplifier/Headphone amplifier kit that was supplied to him by Oatley Electronics in Australia. Their kit the K272 Stereo Tube Preamplifier – Headphone Driver kit is a tiny low power tube based kit.
At only 27AUD its cheap. The kit uses Jan6418 pentode valves but utilises them as triodes. I have not seen a valve pre-amp at such a low price before. I am tempted to give it a try.
Skip over to DiyAudioProjects to see what Mark thought of the kit plus a couple of his implementations, the jewellery box pre-amp is my favourite.
