I built a SVT premap with a solid state 400W mosfet power amp, similar to SVT3 or SVT4. It sounds exactly like SVT's i had used before.
I also did a design for the inductor usign an RM8 pot core.
I did a pcb layout for the preamp, i am more than happy to share all the details with anyone, email me at hotmail.com

Default Ampeg SVT CL Schematic

Hi there,

I am having difficulty with the fault protection circuitry. It appears as though an undesignated 8 pin IC in on the preamp board is defective. The problem also is related to a shorted diode in the same section. I have replaced the diode, but fault mode is still active. Removing the harness allows the bias led's to return to operation.The link to the Ampeg SVT CL has been used more than 10 times and has expired. mroovka could you please send a copy to me at heather.tv@att.net ?

I had an SVT2 preamp. It was available in a 1U rack mount.
I used a 300W power amp i already had.

The sound was the same as old SVT's i had used before, and looking at the circuits on line, it is similar to the old SVT2, the new SVT3 pro, SVT4 pro

I did a pcb layout, and an inductor design. Happy to share with anyone who wants

Yyyyeah, well I did note your posts, but like I said I was looking for schematics to current production Classics. And as someone stated, they were different. Those were for the originals. And I understood mroovka had gotten the later ones from the factory. Right? The ones he was sharing. But thanks for your concern anyhow!

SVT Classic is a current model. We don;t generally refer to the old original SVT as Classic SVT. We generally call that an original SVT.
