Title: Stereomour Plate Choke
Post by: brightcity on August 31, 2018, 04:17:07 AM

Hello, I am wondering the specs on the Stereomour plate choke.

Could someone let me know how many henries the current design uses and the plate current that it is designed for.

Thanks much

These specifications are very much in the manual.

In Stereomour, the inductance from the blue wire (plate) to the black wire (tap for B+) is nominally 20 henries and can handle 55mA; DCR is 535 ohms.

In the SEX amp, or if the Stereomour is converted from 2A3 to 45, useing blue (plate) to red (B+), it's 40 henries at 40mA and 750 ohms.
