I have for sale an Antique sound lab LH-01 combined Valve pre/ headphone amp . Its a pure vacuum tube preamp with a tube regulated power supply and is used as a headphone amp as well as linestage output. There are a 3 line inputs for stereo from line sources. It has a small single chassis design and is perfect for driving small tube amps like the ASL Wave AV 20 or a solid state power amp for tube sound in a budget systems. I bought this for my sennheiser headphones last November direct from the European importer in Germany for approximately £ 490 + Shipping. I have now switched recently to a pair of AKG K1000 headphones and have decided to upgrade to their MG Head OTL32 which is designed specifically for these headphones. In pristine condition, I'm looking for £390 + shipping Technical data Headphone output Regulated power supply Number of Inputs Line 3 Valves 2 x 6DJ8 1 x 6BM8 Frequency 1 Watt 12Hz - 53KHz Distortion 1 Watt <1.7% Current consumption 12 W Dimensions W x D x H 280x175x100 Weight 4.3kg
