Don't you guys have your own websites? I'd like to make a hybrid amp and I need something really working and easy to follow. Thanks.

I'll write up something about my experiences as soon as I get my digital camera back. I'm very happy with my Tube/MOSFET combination. No NFB, all single-ended class-A. The main reasons for trying a Tube/MOSFET hybrid circuit would be to try to retain the tube loveliness while still being able to have hordes of power at your disposal. Well, I'm using my MOSFETS in single-ended class-a so they aren't too high in the power area, somewhere around 40 watts.

Thanks. I'm really looking forward to seeing your result. 40W is large enough for me (and maybe for other DIYers). :-)

This is the schematic overview from harvey Rosenberg's "Understanding Tube electronics" (a 100+ page advert for his New York Audio Labs products).

Something like this or a Zen with a tube buffer would be interesting.

Hi
Moscodes are the best sounding amps around. Check my web page.

I was wondering why it's so hard to find DIY projects of tube/mosfet hybrid amp. Is it because hybrid stuffs cannot make better sound than all-tube or all-solid-state stuffs? What I would like to build is the one using tubes at input stage and solid-state (probably mosfet) at output stage. Any idea, experience or link to a website?

Lot of ideas, lot of experience, lot of commercial secrets. But I promise to make one available for DIY when I will have some time to sit concentrated few hours...

Nelson F4 with a single stage tube front end is very hard to beat.

I used the circuit in figure5 with a irf710 or something like that and a 6n1p
http://www7.taosnet.com/f10/figure3-4.gif
as input stage for a couple of years.. Now it was a few years ago , but I have only good memories of it..
From memory it was 10meg to half of supply and ca200ohm to mosfet gate then some 2k or something on source..
It was followed by some fet stage like in the schematic above but more like the http://www.geocities.com/Tokyo/5913/6922.html
Also did this circuit http://digilander.libero.it/essentia...id_circuit.htm
Hmm.. but I did'nt use it very much, it was only as an experiment.

You can pick them up on ebay.
