Being an electronics tech, I see voltages that are way too high for the designed circuit. Nice looking bucking transformer with stainless cover! Turns device and your equipment on or off. You have a choice of 3% or 7% voltage drop. All vintage tube equipment should be using this voltage reducer. Read on; After WWll and up until 1968, household voltages were 117 volts. Typically voltages these days range from 120-125. Your vintage audio equipment was designed to operate around lower voltages of years ago. You might ask yourself what is a few extra volts? Take into account that the power supply in your vintage device is multiplying those few extra volts many times so that the end result could be 20-30-40 volts more than the circuit was designed for. This could lead to transformer failure, component failure and shorter tube life. As you can see in the photo, the voltage reducer brought the line voltage down from 124 to 116. This is approximately a 7% drop. Simply plug your vintage electronics into the reducer outlet. Will work with equipment drawing up to a total of 4 amps. Has protective 4 amp fusing. Metal box is grounded through heavy duty 3 wire power cord. As an example; Photo shows voltage of Dynaco ST-70 at 467v on todays line voltage and then 438v plugged into the voltage reducer. The correct voltage for this Dynaco amp calls for 435v at this point. Also your filament voltage will be more in line with what it should be. All other voltages are much closer to Dynaco factory specifications with the reducer. Your device will run cooler and safer, extending component, transformer and tube life! Please state voltage drop preference when ordering. Strongly recommended for Dynaco St 70, since they were produced with power transformers designed to operate with 117 line voltage. Your transformer will run cooler, tubes will last longer and all voltages will be closer to where they should be!

Up for sale here is this NOS vintage Knight power transformer, for the Knight S-755 amplifier. This has no ID on it except on the bottom, where it is marked 1005821 101403 (or possibly T101403). 1005821 means it was made by Northlake Transformer on the 21st week of 1958, and 101403 is the part number. This is a big one! I tested this with 120vAC into the primary, and I measured: Thick white wires 5.05VAC. Thick green wires 6.4v. Three thin white wires 409/409/818v. Each thin white wire to the one red wire 372v, 32v, 310v. Voltages always test a bit higher without a load, so it looks like this has a 5v secondary, a 6.3v secondary, a HV secondary of around 800vCT, and some sort of extra secondary with the red wire. This is a really nice transformer, and would work great for building a tube amp. It is guaranteed to work for you. If you know which amp this goes to, please let me know. Please see my pictures for details and dimensions. If you have any questions, please ask. I have more transformers and other vintage electronics listed–feel free to take a look!
