Hi from a newby and Bush TR82C Distorted at high signal strength

I have ordered 4.7MicroFarad 25v Capacitor from RS but these days Axial Caps seem hard to find so through Hole it is!!

Axial and radial caps are both "through hole". As against surface mount. The only difference is that with radial caps both leads emerge from the same end. Axial types are less common now. In many cases this only affects appearnce, not function. With care it's usually possible to fix either type in most locations. On occasion I've fitted radials to older PCBs where the original was an axial stood on end and the result is neater than the original.
