A diy amp which used several ecc88 / 6dj8 / 6922 tubes in paralell for the output.

the chassie was somekind of "minitower" design (it wasnt a computer case but it was height was greiter then the width)

anybody know what Im talking about i cant find the damn thing..
i have missplaced the link

any help appreciated

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.


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:


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!


PS: check the last image, to see if this is it, or reminds of something: http://images.google.com/images?q=E88CC&svnum=10&hl=pt&start=20&sa=N
Here´s the schematic at last!!

By the way, check the site out.
Use http://babelfish.altavista.com and choose translate from Portuguese to English


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 K. Boehm whose e-mail and website are no longer active.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. [:D]
