Echotapper

Obtaining validated information related to the exact parameters of the vintage tapeheads is cumbersum. Jacob extended his capabilities in measuring impedance and kindly offered the values measured to this forum:
The Resistance measured was 400 Ohms and the impedance 440 mH. The heads condition was "used"



Note: The measurements provided are done on perfect heads or stated otherwise. Remember that the principal effects of poor contact between tape and head in play-back & recording mode shows directly at loss of high frequencies. When this loss of contact is due to the gap worn-out state this will directly affect impedance measurements.
