Help with new project...

[Guiness]

Well, I posted a thread regarding a couple tubes that I did not know what to do with, but I think I came up with a idea. Now I just need some professional help. It is focused around the 2c22/7193 tube. Similar to the 6sn7. I have attached a schematic I found on Bob Danielak website for a small power ampifiler. My first question is what do you think? And what would be a good primary on the output transformer. Think I could use a 125ESE? Thanks for the help. I have a case of these tubes and I need to build something with them. Driving me crazy...

3.8k ohms eff plate res, and about a half watt of power.

So I maybe wrong with this idea. but what about using the 5k primary tap on a 125ese for about 300-400milliwatts into the 32ohm secondary to run a pair of grado headphones? What do you think about this idea?

KICKING CANS.

Hi,

If you just want to kick some headphones than that's a hell of a complicated circuit you have there.

Give me one tube/channel and I'll have you a circuit in no time.

KIS,

Yeah I know it is alittle much, but I have these tubes and really have nothing better to do with them. They are very interesting tubes (look like Mikey mouse). Thanks for helping and continue please. Do you think my idea with the 125ese will work?
thanks

Why not go for an OTL style deal with the 6SN7?

I've seen designs using a variation on the futterman style.. lemme look..

eg. http://hem.passagen.se/ebcpecz/Tube/Headphone/images/amp_schematic.gif

you could use a different tube for the gain & splitter. If you used a split (+/-) supply, you could get rid of the output cap(s) as well.

I assume it would like a little higher than 32ohm though. I think ive seen other designs (srpp), but that might just be my brain going funny ;-)
