DIY Tube Amplifier With Old Tv

628.jpg

Hello friends, this is my first publication, and want to show this amp I
did recycling components of an old television tube that no longer worked (had like 40 or 45 years or so).

Remove Circuit Chassis From an Old Tube Tv

This is the TV chassis, are still all components that we will not use

Remove Components That Are Not Going to Use

After finding the audio input, output transformer components and discard (trial and error), we are left with a valve audio (6Z10), capacitors, input transformer, choke, and output transformer:

Make the New Chassis

Wood cutting, screwing and gluing

Putty

Putty to erase imperfections (holes screws, etc.), as the leatherette with which I will cover much copy the surface.

Sanding

Lined With Leatherette

Leatherette glued with contact cement. Many stick with white glue or other adhesives, but cement is the more comfortable I feel.

Faraday Cage

Foil glued to generate a Faraday cage and avoid environmental interference (Very Important).

Presentation

Presentation surface components. I like to look around in the valve amplifiers. Be careful with the armed and avoid touching components when the amp is plugged in

Copying the Circuit

Copying the circuit, having marked each component and its position.

And the End Result
