P1616D Building Process (SUNVALLEY audio公式ブログ)の画像|エキサイトブログ (blog)
All vacuum tubes are included in the "○○ specifications".
* "COSSOR version", "Mullard CV4024 * 2", "Brimar CV4003 / 12AU7WA / 6189 * 2", "COSSOR WE300B * 2 pair", " VCAP ODAM 0.22" uF * 4 pieces "are included.
* "Western Electric 300B specification", "Mullard CV4024 * 2", "Brimar CV4003 / 12AU7WA / 6189 * 2", "Western Electric WE300B * 2 pair", " VCAP ODAM 0.22uF * 4" are included.
The SV-P1616D / 300B specification is a self-bias amplifier that allows you to use various type of 300Bs without adjustment . P1616D is the highest version of the 1616 series.
P1616D is the most unique kit in the DIY market. P1616D is fun to build kit and good to listening power amp.
It is a traditional push-pull circuit + phase inversion design amp. P1616D is a pure class A operation design.
P1616D is an amplifier that you can enjoy the rich harmonics of 300B.
PCB Format
The power supply section, filament section, and ham balancer section, which are complicated to work with, are assembled in PCB format.
POINT to POINT FORMAT
Amplification section is in point to point format.
This allows the builder to have more flexibility in selecting upgraded parts.
Affordability and good sound, ... MADE IN JAPAN kit, SV-P1616D can satisfy all of you.
(Vacuum tube for upgrade)
Mullard CV4024 (2 required)
Brimar CV4003 / 12AU7WA / 6189 (2 required)
COSSOR WE300B (2 pairs required)
(Recommended option)
Vcap CuTF or ODAM 0.22uF (4 required)
(About sound quality tendency)
The SV-P1616D / 300B specification is characterized by the richest harmonic pitch of our amplifiers. Indirect sound components like those heard in a hall, weaving string harmonies and vocal depth ... Enjoy the rich sound that is most typical of tube amps to your heart's content.
