Alessandro Italian amp

Post by Jimmy84 »

Hello.
I am looking for Alessandro Italian schematic or good detailed internal chassis picture.

Any help will be very appreciated.

Best Regards,
Jimmy.

P.S. I if it can be helpful to anybody, I have in my "archives" some "Hound Dog Redbone", "Redbone special" and "Blue Tick" chassis internal pictures.
I also could find "Hound Dog Redbone" preamp schematic.

I didn't think I had photos of the Italian but I did. No schematic. Last photo is labelled Italian Greyhound?

Thanks M Fowler.
I hoped to get some better resolution pics to see resistor color codes. But this pictures are definitely better than having nothing. So thank you again.

Looks like it would be just a simple Fender type circuit with components for 6550 tubes rather then EL34/6L6 power amp.

I've built several similar amps using the Dumble Princeton conversion layout and it is nice even when I made it 22w with 6V6 instead of 100w as the layout shows.

Use the layouts and schematics as tools not paint by number.
