Meticulously handcrafted with precision point-to-point wiring, it features a balanced input paired with a wide-bandwidth input coupling transformer, custom EI-type driver and output transformers, and dual high-power toroidal power transformers for tight power regulation and optimized power distribution. Delivering 160W per unit via a parallel push-pull topology with 845 power tubes, it employs a Full Music 300B driver stage, Line Magnetic 310A pre-amplification stage and 12AX7 buffer stage to produce lush, dynamically expressive tube sound. Fitted with auto-bias circuitry for both 300B and 845 tubes, an external power tube bias meter, soft-start protection, and top-grade components including Multicap capacitors, American IRC resistors, Nichicon capacitors and Japanese Takashima relays, it marries classic tube craftsmanship with uncompromising build and sonic quality.\u003c\/span\u003e\u003c\/p\u003e","brand":"Line Magnetic","offers":[{"title":"Default Title","offer_id":57927034995019,"sku":null,"price":17999.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1063\/0021\/1531\/files\/LM-513PA.jpg?v=1784781605","url":"https:\/\/lmaudioshop.com\/products\/lm-513pa-vacuum-tube-monoblock-power-amplifier","provider":"Line Magnetic","version":"1.0","type":"link"}
