Description
DIY Point-to-point to high-end standards EL84 integrated amplifier One triode per channel in preamplifier section (mirror-connected, when the triodes end their life cycle, you swap them and you have the second triode of each ECC88/6n1p/6n23p/6n6p double triode working)EL84 in power section, pentode connected Amplifier schematic is inspired by Decware, RH84, Emission Lab (for power supply section) with some of my ideas and a lot of testing during one and a half year of development.For any section of the amplifier there were multiple high end parts tested to find the best sound possible. AmpOhm, Audyn Cap True Copper, Amtrans Golden Black, Mundorf Supreme Silver-Oil and Silver Gold Oil, Duelund as interstage capacitors; Solen, Obbligato, ASC, ClarityCap TC în PSU; PRP, Dale, Audio Note tantalum, Kiwame, Takman, Amtrans AMRG, Mills resistors; Nichicon, Black Gate and Elna capacitors for cathode bypass...

IeGO copper/gold IEC.Schurter SPT fuse (tested many fuses, including HiFi Tuning Gold or Synergistic Black, Schurter SPT is the real deal here!) Power transformer, Choke and Output transformers (8ohm and 16ohm output - 8 ohm connected)are handmade in Italy with my specifications (by the owner of gabrisamp.it ). A truly unique amplifier! Comes with 6n1p-ev and 6p14p-ev with 5T3C black anode rectifier - natural, bold, solid sound from these Russian tubesand with one pair of EL84 KM2 series - Mullard Blackburn 60s (Valvo branded) for EL84 tube rolling.Comes with a set of Soundcare Pluto spikes. 230v ! Approx. 19-20kg Needs 95+db speakers for best sound experience.tested with Diatone P610 speakers in Kondo box, Open baffle with Philips 8 and 12inch full range speakers, Coral Beta 10 in original cabinet, Zeiss and RFT vintage full range speakers, Sony SS-3100 (98db/20w three way speakers with new filters with Obbligato capacitors+Duelund Silver and Copper 0.01uF bypass and Path Audio resistors - superb speakers from the 60s), Pioneer CS-A31 (60s alnico three way vintage speakers) with excellent results!
