We used gold-plated RCA standard jackets for the input. It is a normal unregulated power supply circuit. So can provide the circuit with any alternative if possible? This is why star grounding process is probably the best suited in this case. let me digress and the picture will become clear-: I built a dedicated fixed tuned LW/FM Radio tuned Radio 4 with a mains power supply, the racket on LW band was horrendous, after adding a 0.33uF across the secondary winding LW reception was of ‘FM quality’ – this is something I always do when building mains driven equipment. For the input … TDA2030 PCB layout. The circuit design is nice though. As a conclusion, do maintain good thermal contact. : https://www.homemade-circuits.com/32-watt-amplifier-circuit-using-tda2050/, Kindly let me know if I can use the center transformer in this link mentioned below for TDA2050 Split supply circuit: —— PLease let me know ASAP, no it will not work, you must have two separate wires for the center tap, meaning the two winding should be separate and isolated. This cleans all the noises that the National grid generates, the long HV power pylons, switching voltages and stray RF pick up – not forgetting static build up, this includes arching power lines and lightening strikes that could have a short rise time of several hundred volts if not millions of volts so quick a meter will not register. You can also try other discreet diodes that are ultra-fast, but as per this experiment we figured out that it can be ignored and normal rectifier diodes can be used. For the enclosure, here we used Hammond’s chassis [Model ID: 1441-24]– 12” x 8” x 3”, steel built and satin black in color.
