In my build, I am using recycled electrolytic capacitors, and consequently they are fitted sideways and wired into the board. Although in the schematic and board layout there are six electrolytic capacitors, I am using only four and not installing the final ones. This is because I managed to find some very high value ones that did the job well. Hence this part of the build is fluid as it allows the constructor the chance to save money and use recycled components. Here are some photographs of the final build.

The electrolytic capacitors will need a high voltage rating, so that you can have a choice of using a wide range of transformers. The capacitance should be around 1000 µF minimum, though it will not do any harm to have higher values. The 100 Ω resistors are 1 % tolerance and 1/4-watt. The 0.1 µF capacitors are metallised polyester film types. I chosen the 630 V rating ones mainly due to the larger pin spacing as it will minimize the bending of the leads during installation. The strip board is the same size as the one used in the main Baxandall circuit. I felt that a same size board fits more nicely, and the extra space allows one freedom to add fuse holders of one's choice, and larger capacitors. There is also extra space to modify the circuit for the addition of voltage regulators if one wishes, but it is not necessary if you get the correct transformer.
