Need Amp For 90-0-90 V DC
 
I Have one good toroidal transformet (taken form HILL dx1500 AMP) and i would like to use it for a high power amp. Only thing that i found on net is Edwin Paij (Belgium) amplifier -

Anyone made this amp ???

Drafance007 had posted it in his post above. You can find the schematic on the authors own web page which can be reach with the links Drafance007 post as well.

Hi,

Look for another schematics on site

It's the wrong forum, but some 6c33c's in a ciclotron configuration would also work very well on +-90.

+-90 volts are rather much because some transistors must be 250-300 volt types, also many caps must take 100 volts are even more.

The design is very conventional. I think the french guy got inspired of some Elektor amp which had zeners in the diff stage.

I recoemmend also that this amp has DC protection! 90 volts DC in you speakers will get smoke before the fuses blow.... :nod:

What about Anthony Holton
 
There is schematic of Anthony Holton on the page submitted above. It looks like a good amp. Did anyone bilt it? I think I would not work on 90-0-90V.

Sorry for attaching the picture in first post without author permission.

has anyone tried a souped up MOSFET Citation 12? I love Nelson's Citation because it is simple and performs very well. I would imagine if you redesigned the thing, use beefier devices, and add one driver stage (for paralleled output devices), it will still perform well.

Any thoughts?

Jam says he is sending me a Citation 12 to do something with.
I don't think the previous Citation 12 project I did was
particularly popular, but it's hard to resist the lovely little
chassis and supplies the original provides.

On the other hand, I cannot imagine a +/- 90 Volt amplifier
in it. :cool:
