#52: EICO 667: Initial testing
This video looks more closely at the circuitry of the EICO 667 and goes through an initial test. We identify some needed resistor replacements, which must take place before attempting to calibrate the unit in a future video. A nice summary of the model 667 tester, http://diyaudioprojects.com/Testeq/EI...
