The Allnic 61 step constant impedance bridged type attenuator

The L-8000 DHT has the following features:

Line output transformer coupling – The L-8000 DHT is "transformer coupled", using

•

transformers that have been upgraded from those in the L-5000 DHT. In tube amp circuitry,

there are two coupling methods; one is capacitor coupling and the other is transformer

coupling. Capacitor coupling is the traditional, low cost method. It is somewhat stable but

transfers only voltage, not wattage (i.e., not real energy). With transformer coupling, about

90% of real wattage is transferred (there is still a transformer loss of about 10% of wattage –

voltage is not affected).

Transformer coupling is superior to capacitor coupling. However, all the advantages of

transformer coupling depend on the quality of the transformer and on the choice of tubes.

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. Of course, gain tubes are
