The Allnic Audio L-8500 OTL/OCL is a flagship vacuum tube preamplifier that preceded the L-9000 model. Like its successor, it is built using an uncompromising OTL/OCL (Output Transformer-Less / Output Capacitor-Less) design, in which the output tubes-in this case, four 12B4A tubes-are connected directly to the output terminals, with no transformers or capacitors present in the signal path.
