Arrow Do you have a schematic?

Do you have a schematic Maybe at your Homepage?

I made me this homepage in 15 minutes yesterday, just for fun
using www.geocities.com "PageBuilder" - a java Applet

It is a "you get what you see - editor"
Only requires that you can use your Keyboard
and select which pictures you want to put in.

www.geocities.com
- homepages are FREE - with minimum of ads
You can even get several homepage - using different Yahoo-ID:s

One for each subject - Friends, Jesus Christ, family, electronics, music; You name it!

halojoy2000 - Super 15min Homepage


So how does the amp work, purer
and what Tubes do you use?

Gives me somewhat more information.
Please, would give me some inspiration
so I can build my first tube amp, using E88CC

Nice Photo - what camera you use?
I will buy an acceptable digital one.
Can spend $150-200.
Then I can put some Pictures of my Own onto my HomePage

/halojoy - the photo-lover
- have several homepages you don't even know about!

------------------------------------------------------
PS. I see you have a homepage already.
But that page is like "chinese" to most of us.

Get yourself an English Homepage
for all your Audio loving friends to enjoy
Your Work deserves a better presentation
and can give me and others some new ideas!

What you think, purer?
Wouldn't that be something for you? DS

An unusual interesting tube.amp:

A differential input pair of tubes
DC-connetion to an inverter amp Tube
DC-connection to an cathode follower output stage.
DC-negative feedback to inverting input tube
from the load.

VERY INTERESTING -and never seen by me before!

Only one Output Capacitor - rest is DC-coupled
I guess it performs great!
Low distortion.

thanks!
nice of you, purer

Not a differential input as such - IMO just a smart way of avoiding a cathode bypass cap. I'm trying that method at the moment too. It seems good.

Thumbs up Tube OP amplifier

I think you can call it an OPamp Tube amplifier
like OP amp, with inv-noninv input
and negative feedback

and it has a differential input pair of tubes
so called long tailed pair

NOTE my new Homepage with SCHEMATICS !!!!!!!!

HALOMATICS - schematics by a fanatic

Welcome!
