The LV 105u is a hybrid integrated amplifier: tube preamp and MOSFET power amplification. This amplifier has been serviced recently in France by Blue Audio. It's a rather exceptional piece of equipment: the hybrid design with MOSFET outputs is very rare, the circuit is highly complex with numerous current sources, voltage regulation at every stage, and so on. A preheat function is available for bringing the tubes at the convenient temperature before listening. Like every High end equipment of the 80's, it offers a very good MM/MC phono circuit and preamplifier? Due to weight and quality of this equipment, it will be upmost securely packed and shipped with a reliable carrier like UPS International.
