Does anyone know anything about the differences between these series? Other than the different core sizes and physical dimensions, the published specs are the same.
-They're all 0.5W
-They all use M-6 29 ga grain-oriented steel lams
-They all use nylon 6/6 GF-30 bobbins
-They all have a published frequency response of 20~20K Hz., <1dBu and a THD of <0.05% @ 1K Hz.
WSM = EI50 (0.50" x 0.625") Core
UMM = EI38 (0.375" x 0.375") Core
PCW = EI63 (0.625" x 0.5") Core
WSM and PCW have the same size cores, just oriented differently, and UMM has a smaller core.
I'm assuming the larger cores would lead to higher inductance and therefore lower distortion/roll off at low frequencies compared to the smaller core, but that could be wrong.
Anyone else know anything about these?
