Love what you’ve been doing in your vids lately. From the CNC’d compression horn tweeter to this Hiraga amp. John Hiraga has been a favorite designer of mine for a while, and I love what he’s done with Altec speakers and really bringing SET amps back to the masses. They almost seemed like a well kept secret for quite a while. Now they’re extremely popular as people realize the magic of a SE amp or lower powered SS amps like the Hiraga you’re building now. Thanks for the wonderful content.

I would install power supply board in place of the transformer.

[@pcbaudio]

never install the transformer in the center of the cabinet!! best regards

Are you getting 27 watts in class A? That's between 75-100 Watts dissipation? How hot are the heatsinks getting?

[@pcbaudio]

heatsink 300x120x40 is ok

[@mikepxg6406]

how is the 50hz hum...

[@pcbaudio]

There Is No hum noise..

[@tamayaytam]

No soft start, no speaker protection. Why?

[@pcbaudio]

Speakers protection Is next to build It but soft start Is totally useless , i consider It a social media trend
