Resistor Substitution Box, metal film resistors, 1/2 watt, 45 values, 100 ohms – 100K.
RSUB_MFR-L Resistor Substitution Box
Use: Low level signal circuit resistors.
OK, I admit it. You can calculate circuit values until the cows come home but sometimes it’s so much easier and faster to just dial it in. I’ve been a ham and involved in engineering for over 35 years, and I gotta tell ya, these are undoubtedly some of the most indispensable tools I have ever had.
With the low and high value Resistor Sub Boxes, rather than providing resistance decades like most resistor sub boxes do, I decided to provide 45 of the most common values on two rotary switches. It seemed more practical to use the standard values we would most likely incorporate in the amps. The resistors are metal film and are rated at 1/2 watt.
