Am Audio Pa 60x Integrated Amplifier Hifi Amplifier Diy ођ Amt freak said: there have been several requests for a simple and cheap high power amp for djing or pa recently. the circuit below is the elektor pa 300 in a high power version. you can easily bridge it (swap inverting and non inverting input of the opamp in one channel) to deliver more than 1kw rms into 8 ohms. Below is a photo of one channel of the amplifier. the amplifier comes in two different versions: a60, smaller, with 3 output pairs of transistors. a60 , larger, with 8 pairs of output transistors. there are variety of possible versions: with different output transistors. mjl3281a mjl1302a.

As mentioned in the first post, this amp has a double triode at the input. if i remember correctly, it´s a 12au7, a 6922 and a pair of 6cg7 6n6p. the rest of the amp is dc coupled, so my 5 cents would be to look at tube output, guessing through the 4,7µf solen´s. this slow "motorboating" could be a defective tube or some components around it. 2n3055 transistor specifications. voltage rating: 60v. current rating: 15a. power dissipation: 115w. gain (hfe): 20 70. package: to 3. these transistors, known for their robust performance, serve as the backbone of the power amplifier circuit. their high current and voltage ratings make them ideal for applications demanding both power and. Start by mounting the mini amplifier board inside your enclosure. this board is the heart of your portable amplifier and typically comes with most connections pre soldered. solder the 3.5mm audio jack and the on off switch to the board. if your board includes volume control, connect it as well.
