Head-Fi - A Very Compact Hybrid Amp
-
Hello everyone. After much background work and some fair amount of prototyping cfcubed and I (with some help from forsakenrider) would like to introduce a very small hybrid amplifier. This amp was born out of cfcubed\'s efforts to make a teeny tiny hybrid amp as discussed in this thread,Teeny Tiny Tube Amp cfcubed wrote to me about this idea and, as it turned out, I had been…

As from HW, yes this project evolved quite a bit from my original (but not so original concept in that "Teeny, tiny, tube hybrid.." thread. Initially, I was looking for a transportable tube hybrid that would meet or exceed original SOHA performance with size allowing it to fit in a briefcase. Thought that meant using a pencil tube. Wanted muting delay & to avoid SMD construction…

I would be very interested in building one of the prototypes. I've built 2 Starving Students, 2 YAHAs, and will probably build a slightly modified YAHA as soon as my Mouser order arrives. My orthos love hybrid amps.

The Buffer Using an off-the-shelf walwart necessitated some important design constraints. And working within 75mm x 120mm necessitated a few others. Some hybrids use DC walwarts. This is the simplest way to supply DC power to the amp but it tends to limit the B+ to something less than what the walwart can supply. However, if we use an AC walwart, as is used in other hybrids,…

Nice work Runeight and Cfcubed! Should make some great sound, based on your other work. ;-)

Nice work, Runeight and cfcubed! We can always use another tube hybrid in the community!

The Splitter Because the rail splitter sources and sinks the currents in the O/P stages, the "SQ" of the splitter is almost as important as the SQ of the buffers themselves. And so we decided to make the rail splitter look as much like the buffers as possible. This meant a discrete rail splitter with opamp control. Like this: This splitter is essentially an opamp driven diamond…

love it so far! good use of well tested designs.

Hey Runeight, I'd love to give a prototype a try.. Im working on a SOHA + JISBOS, as well as having a 41 Hz Amp6 and a Hagerman Bugle in the process..

Hybrids rule! What kinda tube?(the link for the tiny amp is not working for me)
