STK4221 amp It works just fine Like I said, 5.1 part of the system RL RR FR FL output stage was STK4221 It has been used CENTER and BASS Part PCB Editing after yayınlayacag this circuit PCB organize the I change has been more tidy now, in addition Feed for solid PCB’ve added a stereo for those who use I would suggest Prepared PCB Transformer 2x32v 450 … 500w Output Coils for 4x the 1.5mm wire wrapped on 8 spr can use fountain pens amp NGOs series quite well on the quality of etegre

    Heavy bulky quite strong and a shake 🙂 a power supply circuit is adjustable from 12 … 15 volt regulator integrated 12volt classic L7812 was carried out by increasing the flow of

    Integrated control of the L7812 (12v positive regulator) integrated output power of 1 Ampere output used to strengthen the BD708 MJ2955

    Transformer Troidal you can use a maximum of 25 Amps can give (known price is higher) will be lighter and more efficient, it can be difficult to find the right size cooler do you use a smaller cooler fan cooler to add

    STK4221 amp Es funktioniert ganz gut Wie ich schon sagte, 5.1 Teil des Systems RL RR FR FL Endstufe war STK4221 Es wurde verwendet CENTER und BASS Teil PCB Bearbeiten nach yayınlayacag diese Schaltung PCB organisieren die I-Änderung wurde jetzt mehr aufgeräumt, zusätzlich Feed für solide PCB’ve hinzugefügt eine Stereoanlage für diejenigen, die ich vorschlagen würde vorbereitete PCB Transformer 2x32v 450 … 500w Ausgangspulen für 4x der 1,5mm Draht umwickelt auf 8 spr kann mit Füllfederhalter amp NGOs Serie ganz gut auf die Qualität von etegre
