DIY Tube Amplifier With Old Tv




Introduction: DIY Tube Amplifier With Old Tv

About: My name is Matias Natal and I am an Industrial engineer student, Carpenter and electronics fan with a sustainable approach.

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).

Step 1: Remove Circuit Chassis From an Old Tube Tv

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

Step 2: 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:

Step 3: Make the New Chassis

Wood cutting, screwing and gluing

Step 4: Putty

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

Step 5: Sanding

Step 6: Lined With Leatherette

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

Step 7: Faraday Cage

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

Step 8: 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

Step 9: Copying the Circuit

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

Step 10: And the End Result

Step 11: End

I hope you like it and find many ideas

    Hi , Nicely done. you only use 1 tube 6z10 for your amp for it to produce stereo or mono output?

    Thank you!!! I use only 1 tube (double pentode) for a mono output
