- FWIW, Mike WØBTU put this together, s'plaining the "Miller-Larson Effect": http://www.w0btu.com/miller-larson_effect.html. Though, in some cases (such as in the SB-220), there's little/no benefit, as

- The 10 Ohm resistors only limit the inrush current. They have zero to do with the delay. The delay is set by the R/C values in the coil circuit. R includes the relay coil itself. The delay only needs

- This makes a case that it isn't the rate at which the filament temperature rises, but in stead the fact that it passes through a particular temperature at all. If it passes through ~900F, then the M
