Speaker holder and bracket

I laser cut a series of wood circles to clamp the original speaker then made some brackets out of spare perspex type material I found in the workshop.

Mains cable and capacitor replacement

Before plugging in and testing this radio I replaced some choice components to improve the safety and reduce the chance of damage to other parts of the radio.

The original mains cable was the old twin core single insulation type and had become cracked and hard.

The capacitors replaced were the mains line-to-line cap, aerial-to-chassis earth and the audio output capacitor.

This is my first project in the world of valve based equipment and I’m very excited to be working on it.

I bought it as a non running chassis from eBay but it seemed to be relatively complete, missing only the outer body. This won’t be a problem as you will see since I intend to laser cut a perspex case for it.
