Onda da nabavim one JBL iz oglasa

uuu. ovo izgleda sjajno.

I ja mislim. No ima na onom sajtu dosta toga mi se sviđa. Ovo napajanje recimo bi išlo i na jedno i drugo odjednako https://www.neurochrome.com/product/smps-86-2/

Ja sam za to da neko osmisli kompozitni AMP sa SIT tranzistorima na izlazu. Evo Zen kad se vrati sa odmora.

Imaju skoro isti oscilogram. nije šija nego je vrat

Meni od Dijane Krall

Pitao sam Japanca kako je postigao ono.

Delovi sa gornje slike Antek AS-2222 200va 22v transformer: http://www.antekinc.com/as-2222-200va-22v-transformer/ Shielded IEC connector with power switch and fuse Power-86 https://www.neurochrome.com/product/power-86-2/ Neutrik XLR Hifi2000 case https://www.modushop.biz/site/index.php?route=product/product&path=204_205&product_id=725 Ima varijanta sa drugim napajanjem https://www.neurochrome.com/product/smps-86-2/ plus može da se doda softstart https://www.neurochrome.com/product/iss-intelligent-soft-start-2/

kako izgleda gotovo

Ja ovo mora da nabavim (ili je možda samo ideja nekome ko ne zna šta će da sklapa) https://www.neurochrome.com/product/modulus-86-4/ Ovo je Gainclone ??

Slučajno naleteh na ovo... Circuit Description The Modulus-86 Rev. 2.3 is a composite amplifier providing true world class performance. This performance level is reached by using a specialized audio op-amp to perform error correction on a high-power chip amplifier. This Neurochrome composite amplifier topology results in a high-performance 65 W amplifier with vanishingly low distortion and phenomenal sound quality. The Modulus-86 is a turnkey analog subsystem. It requires no adjustments and it achieves state of the art performance using readily available off-the-shelf parts. The Modulus-86 uses one channel of an LME49720 precision audio op-amp to perform error control on an LM3886 power amplifier. An OPA2277 precision op-amp is used as a high-end DC servo with third order filtering for an ultra-low output DC offset and fast settling time. The DC offset is less than 200 µV and is reached within ten seconds of power-up. A THAT1200 differential receiver provides common-mode rejection rivaling that of a line transformer, thus, minimizing hum injection by eliminating ground loops in the signal path. The Modulus-86 is power supply agnostic, which is a unique feature to the Modulus-86. Due to the error correction provided by the Neurochrome composite amplifier topology, the Modulus-86 performs as well on a traditional unregulated linear power supply or a switch mode power supply (SMPS) as it does on a well-regulated laboratory power supply. Key features of the Modulus-86 Rev. 2.3: 70 W (4 Ω), 40 W (8 Ω) output power when using the Power-86 and recommended transformer. Mono construction: One Modulus-86 board per channel. On-board error correction circuit with local low-noise power supply regulators. Ultra-low 0.000054 % (-125 dB) THD (1 W, 8 Ω, 1 kHz). Ultra-low 0.000088 % (-121 dB) THD (40 W, 8 Ω, 1 kHz). Ultra-low 0.00042 % (-108 dB) THD+N (40 W, 8 Ω, 1 kHz). Differential input with nearly 90 dB CMRR eliminates hum and ground loop issues. Differential/balanced/XLR input can be used with single-ended/unbalanced/RCA sources as well. Power supply agnostic. The phenomenal power supply rejection ensuring consistent, high performance even with unregulated power supplies and switch mode supplies. Ultra-low -120 dB inter-channel crosstalk in stereo builds greatly simplifies the power supply requirements. Elaborate use of planes and copper pours to maximize circuit performance by minimizing supply and ground impedances. Low-inductance signal ground connects to power ground at one point only for maximum performance. On-board Zobel and Thiele networks for maximum stability even with capacitive loads. On-board EMI/RFI input filter and ESD protection. Power and output terminal blocks accept wire sizes up to AWG 10 (5.2 mm2). All thru-hole construction with socketed ICs. Easy to solder. 90 × 70 mm board footprint. Bill-of-materials includes a Mouser Electronics Project Link for ease of parts ordering. https://www.neurochrome.com/modulus-86/ bolest

Ovde je jedino problem kako spakovati nuklearni generator struje od par kilovata u đepno izdanje... Sam pogon nije toliko velik. (nije veći od motora Boeing 747) Problem je napajanje

Evo ga SIT u NASA EM drajv pogonu. Ovde je od par kilovata komad. Veći tranzistor nikad nisam video. Mikrotalasi su na izlazu ovog bakrača toliko jaki da proizvode potisakv 333mN/KW. Postiže se sa njim brzina 3 km/s u aero tunelu

SIT koji svira na 4Ghz . 30W ima jedan sa gainom od 10db na 2Ghz

SIT je Izmišljen za vojne potrebe . Evo pdf ovde sa detaljnim tehničkim osvrtom (završava se domen na .mil) http://www.dtic.mil/dtic/tr/fulltext/u2/a299605.pdf Teško se učitava pa ču da ubacim kao atačment. Nisu ni zamišljeni da sviraju u normalnim audio uređajima. Pošto svašta nešto zabranjeno možete da napravite sa njima povučeni su iz masovne proizvodnje.... Recimo sa par komada može da se napravi ometač signala od 20W da blokirate sve signale na 2Ghz u pola BG Ruski Krasukha-4 system za ometanje radara JE PUN SIT-OVA koji sviraju. Dabome Zato ih prave po potrebi i po nameni (narudžbini). SIT.pdf

Ali i sa njim prave pojačala

Samo je drugačije kućište za liftove

Ovo je slika od Kineza ... Ima ih

To je ovaj kapiram https://www.ebay.com/itm/1pcs-NOS-THF-51S-THF51S-TOKIN-V-FET-SIT-NEW-japan/123370081778 stavio sam i Japanca i Kineza...Kinez ima dve ponude

Ovi kad rasprodaju Tokine....Ovo vade iz nekog magacina, zalihe od pre 20 godina. Možemo da duvamo u prste.

Ovde veoma lako može da se naleti na fejk. Ako je Kina
