SUQIYA Finished Hifi DIY FM711 Stereo 260W+260W Amplifier Beyond DarTZeel Sugden Amp

Reference Price 638000 FM711MK fever famous machine line sound is noble and gorgeous. Compared with similar boards, the audition improves several levels..

FM71 rear-stage amplifier board complete machine installation wiring diagram is as follows:

Partners are using QT-2A transistor graphic instrument to pair the power amplifier used

Basic materials:

Power Tube: 20 new imported ansenmei MJ15024G pairs.

Small gold tube sealing: 2N3440,2N54164 total 16 pairs.

High-power resistance: US military grade Dani resistance deep black color high power 18 pieces in total, each one costs more than 3 yuan (not ordinary white ceramic resistance used for similar products online) these 18 resistance pairs determine the whole board occupational stability and sound quality, so it cannot be saved.

Get rid of these costs

Electrolytic capacitor: imported Philips BC, Japan Ina

Nonpolarity capacitor: New Swedish EVOX RIFA imported EPCOS film Rijing NIS Japan Murata

Power filter pond: new imported Japanese origin genuine goods Black King Kong 80v 8200UF 8 pieces this is the original machine parameter (not the shell leather shell capacitor used by similar products online)

Resistance: American military grade Dani resistance. Japan Shuangyu.

There are many options for transformer selection:

Recommend transformer with a total power of 600-1200W,

Solution 1: double cattle (two transformers) each transformer has an output of more than 300-600w, double 35-50V (output 3-wire or 4-wire is OK) and a single 12v winding is added, supply Protection Board two same Transformers each Channel One

Solution 2: single cow (1 transformer) transformer 600-1200W or more output double 35-50V (output 6-wire or 8-wire means two sets of independent double power supply winding are designed on one transformer) in addition, two sets of single 12v winding are added to supply the protection board.

Rectifier Bridge and filter capacitor:

We recommend that you use two 50A skateboard support, and each group of 4-wire output cows is connected to a rectifier Bridge, and the rectified positive pole is connected to the other group of rectified negative when GND, the other two sides output VCC and-VCC respectively,

(Separate power supply for each channel).

Output power: 8 ohm load — 260W * 2

4 euro load — 500W * 2

4 euro load — 800w * 2

Enthusiasts want to ensure the maximum output power, so the transformer selection should be large enough
