Go big or go home.

I feel like I'm maybe the only one left here... got out yesterday for another blast through the local woods.

So I've been looking at a bunch of tube/solid state hybrid dynamic amp schematics, and every one of them is some form of bad, or really bad. (one person/ex company in particular) Low voltage plate, capacitve coupling of a high impedance source into a low impedance, poor balance etc. There had to be a better way. true balanced input. dc coupling. low impedance output. no feedback. proper use of a tube (pure transconducance) etc so I came up with this, work in progress. 4 x 3 inches ubaltobaltubeschem.PDF

Happy belated! (party favour noise)

FWIW I've use them as output transistors on Dynahis and CFAs without problems. Got significantly better N-P matching on them compared to the MJFs as well by the way.

Same pinout so they should work

Happy Birthday!

Happy Birthday!

Pics will be forthcoming. I think I'll probably do the medium, but I haven't had the large on my wrist. The Medium has more surface area than my reverse, but the Grande Reverso is nearly as tall as the large Santos. I'll likely give the Reverso to Colie after I get the Santos, so I have to really think about it!

Yes, the medium or the large. Brain fart.

Happy birthday my friend!

Happy Birthday HiWire!

I should ride this weekend

Happy Birthday!

My mother wants to buy me a Cartier Santos, this coming weekend, apparently. She bought herself a medium (along with a Tank A), and wants a matching watch with me (which she already has, as we now both have and wear Rolex GMT Masters and Speedmasters, but whatever). I'm not going to complain. I dunno if I'll choose the medium or the small. I go to try them on tomorrow after work. I'll take my GMT and my Reverso, to help me decide. I feel like I'm right in between. The bold choice would be the medium.

Or just add a real analog noise maker to your city car ...

And their free company shuttle buses keep getting stoned by people who live off the taxes they pay and hate them for it. Who'd be a tech bro?

Rice with seafood and second, baked cod.

here are both of them, not sure which one was in the group buy 3) Its a current mirror. So output voltage depends on impedance, currently 1100 ohms. Needs an output buffer if you are going to use it for a preamp.

Switched back to the road today.

don't let any of the idiots over there know about this, the first thing that will happen is that someone will plug the tubes into a bhse directly and destroy $2k in tubes and probably trash the rest of the thing. these dht's have virtually identical curves to 6ca7 in triode mode.
