The kit is very easy to assemble. It works as described. Yes a very good product.

Nice kit but a PC board would be nice, I would be willing to pay a little more for it.

Easy to follow instructions, easy to build. Works fine. I would recommend securing the AC cord to the wood base using a cable clamp in case the cord gets yanked. Radio Shack has them, model #64-3028. Also, don't earth ground the circuit return (B-) either with a three wire ac cord or on the radio itself. As wired per instructions, there is no earth ground reference on any of the secondary voltages which reduces the shock hazard if you happen to be grounded and come into contact with B+. It's also true if you are wearing headphones wired in series with the plate supply of the radio's audio amp and a fault occurs. If you need an earth ground on the radio for a counterpoise, do it through a .01 mfd capacitor 500 volt rating or greater.

Excellent kit. I have purchased a couple of them in the past couple of years. I use one as bench supply for testing and troubleshooting antique radios. The other was permanently installed in a vintage Crosley "farm radio." They have both performed reliably and the kits are more economical than ordering separately transformer, diodes, capacitors and regulators.

this product is quite excellent and works very well as a power supply for old battery radios. The zener diodes could be better labelled as the writing on them is quite small. Overall, I recommend this power supply.

It's great to be able to buy a well designed ABC battery eliminator for old radios with all parts furnished in a kit. The instructions are adequate and it is easy to identify the parts and polarities using the very clear illustrations. I was pleased that it worked perfectly when I finished soldering (using alligator clips as heat sinks) and am happily using it to power a 1925 Grebe Synchrophase farm radio that requires 6 volts for the filaments 90 and 45 volts for the plates (detector needs 45, all others 90) and -4.5 volts for the grid bias.

There are a number of items that are not supplied with the kit that I found it useful to add, and I'll mention in case they are of interest to others. They include an on/off slide switch (mounted with double stick foam tape to the side of the transformer); a fuse holder (mounted with a screw to the side of the wood block below the transformer); a three wire power wire (so I could use the green ground wire as the ground connection for my radio); two cable clips to secure the AC power wire to the wood block (I think using unsecured twist connectors for 120 VAC may pose a safety hazard); and a red LED (in series with a 220 ohm current limiting resistor) across the A+ and A- terminals as a powr on indicator.

For connections to the radio, I purchased 8 conductor, 19 gauge thermostat cable at Lowe's. Seven wires were used for the ABC power connections and the eighth for the ground connection. I secured with cable clips at the radio and power supply. This approach makes for a much neater installation than using individual wires.

Lastly, I found 9 conductor male and female power connectors at Radio Shack. When I buy another farm radio, I plan to insert these into the thermostat cable so that I can easily move the power supply from one radio to another.

I have used several of these for customers and myself. They are well worth the time to assemble. Thank you.

I received 2 incorrect diodes I should have 10 of one type and 2 of another but received all 12 the same. Also a capacitor is incorrect as well.

I liked this P/S so much I bought another one and plan on buying even more. Thanx
