Well, two of the 11V Zener diodes were missing, and one of the 15V was just bad. The circuit diagram is difficult to translate to the tabs provided, so frequently found myself switching between the schematic and layout diagrams. Built it out, substituting and making a couple of minor changes to the circuit for the missing 11V Zeners, and I was able to get B voltages within a few volts of the reported output. Good enough.

A little more attention to quality control before they ship out the door, and maybe a couple of minor circuit changes, and I'd have given this a 5 star rating instead of a 4. All in all though I'm pretty pleased with the overall kit and it was fun to build, just not totally painless due to a two missing and one dead-on-delivery diode.

After building it, I didn't have any "B" voltages. After trouble shooting and taking it apart, realized that I was left with a LM317T for Q1. What is "Q1" supposed to be? I probably have one.
For the price, a circuit board should be included.

Easily assembled as long as you have basic soldering skills. Inventory parts carefully. I was missing one small part. It was immediately replaced for free. Voltages of 90 and 135 a bit low, don’t know exactly why, but they are close enough for the radio I tested to work great. Nice kit.

It's a very nice product it's doing a fine job on my RCA 55-F

I have owned this kit for several years now. Although it is rock solid reliable, the filtering is very poor. It generates a lot of noise, and depending upon the farm radio you hook it up to and where you use it in your house, it will manifest different symptoms. On a Silvertone Model 1926, I would hear a slight hum with the volume turned down. On an Airline 62-305 it generates hum when tuned to a local station on a particular frequency and, depending upon where I use it in the house, there is static in many areas of the dial. Also, when this power supply is in use and another radio is on elsewhere in the room, you hear a bad hum on the other radio. Turn the power supply off and the hum on the other radio goes away completely. It's time AES took a second look at the design of this kit and improved it. If the power section of AC radios in the '30's and 40's can effectively eliminate all AC hum and static, then why can't this 21st century battery eliminator? Also, I question the wisdom of using a single 4700uf capacitor to filter the filament power. In my experience, the higher the value of a capacitor, the more likely it is to leak and loose value over time.

Nice product but found two problems. One was an incorrect resistor which I determined was an honest mistake because of an orange band appearing to be red, and I also have a tiny amount of AC hum in my speakers that I believe is coming through the 301A tube filaments.

I still have the set but bought an ARBEIII and problem solved.

Appears to be a great set but I had one part incorrectly installed prior to shipping same as the last reviewer I am hoping to rectify the issue with AES soon

I spent today building my kit and it was a very straight forward process until I went to test it. I was not able to get any B- or A+/A- voltage. I spent about 5 hours troubleshooting checking my work and redoing connections. After giving up decided to remove the LM317T and test it and guess what ? Whoever put this kit together, mounted the TIP47 to the heat sink and left the LM317T loose in the bag. This means they were installed wrong. I would ask for better quality control in your kit process. I wasted alot of time today on this. Thanks, Ron
