No direct help I'm afraid.

Sounds like a TdP EAR V20 to me. If you could track down a schematic you could do something similar.

Oh and if you do please post it here!

How about this

It's still under development though (not by me)

Micke, I am thinking in similar terms as Lee. Topology fits the bill, but the cab does not come close. Tim de Paravicini used 12AX7s in a balanced bridge mode. I have a lot of respect for Tim. He is a very clever designer and an original thinker.

Lee, Which software do you use for drawing schematics. I am looking for one.

HI!

Yup, I think i know what you're after. A sweet kinda tower with four E88CC and a 7F8 in the middle in one end, right?
i found, hardly, the link:

www.ndh.net/home/kboehm/

Unfortunatelly, i needed it cause i lost the schematics and, with all the material ready, i had to have it. BUT, the site is deactivated. It's a 2 channel 1W amp.

Man, it's sad. I'll try to find something in my computer, perhaps it's somewhere in the ends of the FAT file system.

Mohan, try www.cadsoft.de The Eagle software is free and great!

Bye!

PS: check the last image, to see if this is it, or reminds of something: http://images.google.com/images?q=E8...&start=20&sa=N

Thanks Petman. I have just downloaded the Eagle Software.

Petman · 5th May 2002, 11:08 PM

Guys!

I found the printed schematics! As soon as I can i'll post it here.
BTW, do they need to be online to be posted or are they uploaded to this site?

Bye!

Petman, if you keep them smaller than 100kb and 800 x 600 pixels you can attach them to your post .... if they are larger than this, you have to link to them from an online source.

Petman · 22nd May 2002, 08:14 PM

Here´s the schematic at last!!

Url: http://www.geocities.com/freespeedpro/1W-se.jpg
By the way, check the site out.
Use http://babelfish.altavista.com and choose translate from Portuguese to English

Bye!

PS- this schematic is from Mr. K. Boehm whose e-mail and website are no longer active.

For those who visit my site, you are warned that you'll get a hell of a laugh, due the the great translation process of babelfish. Tobbaco should read smoke, ponnies should be BHP. [

Due to the joys of the limitations of geocities, the link posted above will not work. You must goto http://www.geocities.com/freespeedpro/ first and then change the address bar to http://www.geocities.com/freespeedpro/1W-se.jpg
