2) The ERF-2030 is not an ‘electrical drop-in replacement’ for the 2SC2166, 2SC1969,
and 2SC2312. However, circuit modifications on most radios are minimal and
documentation is readily available for FREE.
3) The ERF-2030 is a ‘mechanical drop-in replacement’ for the 2SC2166, 2SC1969, and
2SC2312. This means that the ERF-2030 features a TO-220 package with the SAME
pinout configuration as the 2SC2166, 2SC1969, and 2SC2312. Therefore, NO
mechanical modifications to the ERF-2030 are necessary for most installations.
4) EKL Components manufactures a series of companion parts to the ERF-2030. The
EN-1230, EN-369DR, and EN-369FN are available to make radio modifications
easier and maximize performance.
