Quick power and audio testing unit \u00a02<\/p>\n

\"\"<\/p>\n

Build a powersupply \u00a0based on LM317 & LM337, \u00a0 with 2 x 15ac Volt and 1 x 9ac volt transformers<\/p>\n

\"\"<\/p>\n

Oeps some huming<\/p>\n

\"\"<\/p>\n

Tested with 2 x18ac volt x 1 x 9ac volt, \u00a0Much better results.<\/p>\n

Testing with newly build power supply<\/p>\n

New Design power supply, \u00a0a render without heatsink.<\/p>\n

\"\"<\/p>\n

The new powersupply<\/p>\n

\"\"<\/p>\n

 <\/p>\n

\"\"<\/p>\n

Is the powersupply quiet – Digital silence<\/p>\n

\"\"<\/p>\n

Multitone – 20 dbBfs<\/p>\n

\"\"<\/p>\n

Building new version off the power supply, the old design worked correctly but produced to much heat \u00a0, testing bigger heat sink<\/p>\n
