Quiet switch mode power supply (SMPS) for KiwiSDR
Now working fine 24/7 with an 5V-IC featuring maximum 5 A in a TO-3 housing.

Unfortunately there are some fakes on the road, which disguise themselves in TO-3 housing, but never deliver the higher load current than approximately 1A. However you can easily sort them out by having a look on the mounting side. Some butterfly-like chip welding got the original ICs. This characteristic construction sign is valid also for other voltages e.g. 12V ICs as I could recognize.
