Hi all,
I have for sale a very very good sounding amplifier from our member dadod!
Thread to the amplifier:
https://www.diyaudio.com/community/threads/lateral-cfa-120w-bsa.338814/
I am using a big and oversized custom wound toroidal transformer with a soft start module. Filter caps are 4x RIFA 33 000uF 71V. Amplifier has separate power supply modules for each channel. It is a capacitance multiplier with overcurrent protection and output DC protection.
Thread to the PSU:
https://www.diyaudio.com/community/...multiplier-with-electronic-protection.205520/
Lateral mosfets are mounted on a big piece of copper for thermal heating. Between copper and aluminim there is a CUPAL metal sheet (https://www.promet.com/en/products/sheet-metal-technology/cupal-metal-sheets.html). Source resistors are non inductive. Resistors in current feedback are Vishay Dale. Everything is made with nice quality parts.
Measured power output @8R is 117.8W and 174W @4R. Pout on 4R could be higher but the overcurrent protection kicks in. It is limited to 7A (the limit can be omited).
Case that I used is this one: https://modushop.biz/site/index.php?route=product/product&path=207_277_279&product_id=222
Sound is just amazing and I hate to sell it, but dadod made another project Class A + Class B that I would like to make and I don't have enough room to have two amplifiers.
Location is Croatia.
I would like to sell for the price of the parts that I paid and that is 1200€.
For more information or negotiations, contact me, I don't bite 🙂
Thanks

Happy New Year to everyone.
Little bump!
This power amp is a really nice match for Gainwire CFA preamplifier that member dadod also made. I can give a PCB free for anyone that wants for buy this. I also have a pair of boards for this amp that I can also give.
I am open for conversation.
Regards
