power amplifier design

Hello, I am replacing the power capacitors in my 1980's Advent 350 Receiver. The capacitors chosen require I increase the ampere rating on the power rectifier diodes. The OEM Diode part number is YAB-010EDI7945. I have not found any cross reference for this number so currently do not know the...

Firstly, I would like to say, this is my first Fosi Audio product. And so I would like to mention that the build quality and the sound is great, no clicks or pops, and no dreaded white noise whilst on standby. Especially at the price. I've definetly been swooned. Now my actual question is...

I just built a power amplifier module based on the Trimodal Power Amplifier by Douglas Self. This is part of building a complete integrated amplifier. I'm now working on the preamplifier, power supply, PHONO preamp, input switching, speaker protection and maybe remote control unit. For those not...

DIY 250W/4ohm power amplifier based on “blameless” topology Hello all, the thread posted here by @sabristol https://www.audiosciencereview.com/forum/index.php?threads/luxman-l-85v-integrated-amplifier.20657/ inspired me to build a new DIY amplifier functional sample. The circuit posted in the...

And so begins yet another needlessly complex project. I should disclaim before the talk of how dangerous dealing with multi-kV systems is and how I'll hurt myself that I'm in my last year of an electrical engineering undergrad, so I know how to work with high voltage safely. I'm in the design...

This is a project I did last year - a mid 70s Luxman L-85v refurbishment with a re-engineered output stage. The output stage PCBs were damaged in the early 1980s I've I had this amp kicking around since then. After 30 years, I eventually decided to try designing and building some replacements...
