Page 4: Introducing The L-8000 Dht Line-Stage Preamplifier
INTRODUCING THE L-8000 DHT PREAMPLIFIER Allnic Audio and the Direct Heated Triode Breakthrough In the early years of the last century, the directly heated triode was invented independently, and almost simultaneously, in the USA and Austria. This simple device, an anode, cathode and a grid in a vacuum contained in a glass bottle, transformed the world. - Page 5 Like the Allnic L-7000, which is an indirectly heated triode preamplifier, the L- 8000 has a noise floor that is effectively absent. The Allnic L-8000 DHT preamplifier is the improved successor to the L-5000 DHT, which was THE WORLD’S FIRST COMMERCIALLY PRODUCED, PURE DHT PREAMPLIFIER.
- Page 6 Allnic Audio manufactures its own transformers and uses what it views to be the best core material, Permalloy. Allnic Audio's unprecedented, wide (16Hz ~ 75kHz, -3db), low distortional, and ultra-flexible (up to 50kHz square wave response) output transformer helps Allnic Audio to realize the ideal transformer coupled preamplifier.
- Page 7 Low output impedance is critical to the design of a good preamplifier. The L-8000 DHT has a 120 ohm (120Ω) constant output impedance at all frequencies. In capacitor coupling (C-R coupling), a “cathode follower circuit" is usually used to lower output impedance.

We advise that you keep the box and other packing materials that your L-8000 DHT came in. It will be useful if you sell your L-8000 DHT or in the unlikely event you need to ship it for service. SAFETY CAREFULLY and SLOWLY remove ALL cardboard and Styrofoam cushioning material inside •... -
Page 9: Cleaning
INITIAL SET-UP LOCATION, LOCATION, LOCATION Like all audio products using tubes, the Allnic Audio L-8000 DHT needs to be placed on a solid stand in a location that provides for good air circulation around the preamplifier. DO NOT cover the top of the preamplifier. -
Page 10: Inputs
NO PHONO STAGE - The L-8000 DHT is a line stage preamplifier and does NOT have a built in phono preamplifier section. You will need a phono preamplifier if you want to use a turntable with the L-8000 DHT. -
Page 11: Initial Power On
Push the power on-off switch to the left of the IEC connector (facing the left side of the unit as in Figure 1) so it is in the “on position”. That will power up the L-8000 DHT. From this point on, you need only use the far left hand button marked “power”... -
Page 12: Operation
“on” position – this will keep key circuitry warm, and your L-8000 DHT will be ready to play when the soft-start turns on the L-8000 DHT next time you want to listen. Turn off your sources last. -
