Hi,
I have a home made 13,8V x 25A linear power supply that uses LM723, TIP31 and four 2N3771 power transistors. This psu is used to power my YAESU FT-757GX 100W HF rig. How do I filter out rfi feedback that could come in to the LM723 voltage feedback line?
In the past I found a site where they learn how to modify or repair ASTRON power supplies and there was a topic like LM723 RFI filter but I can not find!
