hello, I build very high-end amps/preamps, and I would like to use switching power supplies, but I would like to have ideas for filtering the background noise as best as possible – I achieve good results, but perhaps there are simpler solutions.
Hello,
I am a Ham Radio operator and have dabbled in PCB creation. I have a go box which houses my radios main power 12vdc. I have a hand mic and speakers and have a headset with both mic and earphones. I am currently switching between the two using a mechanical set of relay SPDT switches. I would like to create a PCB with a electronic solution.
Any Ideas?
Hi Tony,
I’m also a Radio Amateur, I also do various PCB Layouts from Circuit Diagrams.
You can look me up on QRZ and if I can help you, I will try as best as I can.

Hi, yes, it is possible. You can replace the mechanical relays with electronic ones by building the circuit as explained in the following article: https://www.homemade-circuits.com/12v-dc-solid-state-relay-ssr-100-amps/
The MOSFETs can be replaced with ordinary BJTs, depending on the power of the load….
Hola estoy tratando de adactar el modulo egs002 a un inversor quiero usarlo para obtener Una Salida a 120v tengo Ala Entrada de los mosfet 140v pero no me esta trabajndo me parapadea dos vese el led q pudiera ser
I would like to use your 10amp regulated power supply circuit using LM 317 and IRF9540,in a dual supply configuration for an audio amplifier. Shall I use LM337 and IRF540 in similar manner or shall I use the same circut to regulate the positive to common? This will necessitate using another transformer doubling the cost. What is your suggestion?
In cd 4060 circuit, when supply cut and come again, the circuit trigger, without triggering manually.
please give solution, so false triggering can be prevent by power supply failure.
When we require to on timer, then it should be operate only. So give suggestion.
