Amplifier Upgrades From New Or Recycled Circuit Components

LEAD A MARCHING BAND STRAIGHT THROUGH THE GRAPEVINE. These YouTube releases from the artists certainly sound cleaner than the vinyls in my collection.

Cosmo's Factory on vinyl still has slightly more feel through my amplifiers.

I add capacitance to the power-filter circuit inside the amplifier which allows lower frequencies to pass with less signal attenuation.

Since I have to shop and order a pair of audio grade capacitors for one of my amplifiers, I will share. The process IS dangerous and requires a method of draining the existing capacitors before removal. The safe way is to use a ground wire with a resistance in series to prevent sudden discharge from the capacitor. Else many just use insulated pliers to short the caps to the case/chassis. The capacitors are usually very easy to identify in the circuit while replacements and upgrades can be ordered online. A way to have an average amplifier perform like a much more expensive model.

The cheap method is to recycle a computer power supply by removing it's 200 Volt capacitors to connect them in parallel with the existing capacitors inside the amplifier. This also does a good job of providing greater low-frequency fidelity to the source signal.

With preparation the amplifier should not turn into an ample-fire.
