Simple hybrid amplifier

[FOXYE]

Hello,

Is there any simple hybrid amplifier schematic/projects that recommended for construction?

Like the hybrid amplifiers from CROFT:

An externally hosted image should be here but it was not working when we last tested it.

Showing the chassis doesn't help much. The simplest one I've seen, don't know if it's good or bad.

Do you have more information about the amp?

And how much power the amp can supply to 8 ohm?

Hi Cassiel!

Do you have more detail about this MJ hybrid amp??

No, sorry, only the schematic. Got it from the Solid State forum, maybe if you ask there....

Good request foxye, i'm also interested in hybrids especially now that i have plenty of bjt's from ON Semi to use as well as power Mosfets to use as output buffer and looking for stable one.

also, maybe someone kind enough to share some schematics with Triode-Pentode tube as inputs. Like 6f5p or 6bm8, triode section as voltage amplifier and the pentode section as cathode follower...any schematics please?

ELLA
It works! I tried with Hammond 125FSE.

last blog from Tubecad goes into hybids. I think that something like the first schematic, with OPT instead of the 2k5 resistor could work out quite nicely.

Supercharged Output Stages

but there are zillions of way to make simple hybrid amplifiers.

Mr. Turner just presented a design recently, like everything that he does, it is very well documented, check it out here.

Darn, I recently 'invented' the circuit you just linked jazbo8 !!!

Well, goes to show that it's a good idea ! - Mr Turner has an excellent website.

I recently presented the C-Vac concept. It isn't a hybrid in itself, but it allows you to build hybrid amplifiers from a pure tube source schematic.
For example you could translate a tube direct-coupled headphone amplifier into a speaker capable amp, and that is true of any tube topology.

An application is shown here, the SolidGlass amplifier:
