Unknown Vintage Tube Amplifier Heathkit? I don’t know who made this amp but it powers on and seems to work. As it heats up it has a smell to it. I know it’s better to slowly bring up tube amps so you don’t fry them so I just powered it on for about a minute to test it out. See pics and video demo. The volume and tone controls seem to work and on the the back the ohms are label on the speaker outputs. I only tested the “Tuner” input on the back.

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!

This Heathkit EA-2 was tested with a MP3 player into the crystal cartridge input and it sounds great! Of course, it sounds better in person! You’ll notice when it’s turned off, it kind of fades away as the capacitors discharge and the tube filaments loose power! The filter caps have been changed as you can see. There are a couple mods done by the previous owner. One is the addition of an output jack for a recorder (see close up pic), the other are diodes on the 6X4? Tube socket so the tube is not necessary. Looks like all you have to do is remove the diodes and a tube can be used again (see close up pic). Cosmetically it’s very nice showing just some minor wear. It may or may not work at all when you get it!
