HYBRID- Schematic

[jleaman]

Anyone got any hybrid schematics they want to share ? I have a few but always looking for more and other schematics to concider building. Im looking fora tube front end and a fet out put stage I have yet to find a class a output stage only Class A-B..

Any one ?

It is a simple matter to bias a complementaru MOS output stage into class A - usually a single resistor is changed, so I really don't see what the problem is

I so far like this project and i am going to tackle it. I cant for the life of me find the author.. I plan on changing some parts though..

I think I'll give that design a go as well, would you have the schematic for the power circuit? I'm wondering how I should go about making the power supply to give me +35VDC and -35VDC...... a TLE246 maybe?

Im going regulated. Im also going to do it with just the standard bridge rectifier with a 6.3 vold and a 35 + - capacitance bank. Just a simple circuit. The ill start changing values maybe change the tube then of course the out put transistors to other ones that could handle more current. Maybe add 2 more out put fet's THEN ill go regulated psu and regulated psu for teh tube..

I'm trying to figure out how to make a tube part in Eagle GOOD luck with this for me > O (

I'm pretty new to the tube scene, and so far I've only had goes at building hyrbids. Would it be too rude for me to ask to have a look at your final schematic? I really would like to build a nice sounding hybrid because my first hybrid using sijose's design on headwize wasnt all that great.

thanks

Hey hey
I'm making my hybrid amp such as above schematic.
Here's power supply schematic in the attached file .
Furthermore, I enclose add of original web.

Jason,

For a good explaination of this Borbely linestage ripoff and how to improve and enhance it go to www.tubecad.com and download March 2001 and then April/May 2001. Have fun! Somewhere on that site is correspondence from Erno Borbely regarding the schematic you have posted.

Cheers,
Steve.
