This is one small and “cute” amplifier . Very easy to build, due to with initial sch , there is no additional space for setup . Recommended transformer is 2x15V

What to say, if everything is already written at the Silicon Chip magazine. I built it and make it as kit. Due to many small and quality capacitors which are

Before 5 years (4.9.2016) dr. Bora Jagodic was left our world and continue his great work I hope on better place. In the memory to him and his contribution to

Dear visitors, long time ago I wanted to build an HiFi amplifier with tubes . Personally , I think that discrete components are much more advanced compared with tubes however

This is one of amplifiers which I want to build long time ago. It is built in many variants and it has many tweaks, however I choose to build Grand

For the 1st year anniversary of Hifistor company I would like to share this Hiraga 8w amplifier build, codename Maria with all visitors. Many times I asked myself what will

King is dead – Long live the king , probably is the word which can describe this project . After many months of designing, parts ordering, speaking with people and

This is one of the most popular A class amplifiers.  I used the original board layout shown in the magazine article (as well as the original driver transistors. However, due to

This is another very popular build form mr. Nelsson Pass . It is a 30W A class power amplifier. All output transistors need a huge heatsink and after build it

 This is the schematic of the very popular small A class amplifier Jean Hiraga 8W. The original Hiraga Amp transistor are replaced with 2SC1845+2SA992 and on output MJL21194G+MJL21193G which is the
