My mistake. Upon further investigation, I found one of the pins on the generator output fouled with grease. Once I cleaned it with a mild degreaser, all worked well. Just an FYI for future buyers and an apology for my previous post. Also, I ended up with a model 40 which as a previous poster stated will produce either 12VDC or 15VDC depending on choice of cable, works very well for both applications but this unit did not come with any spare parts as advertised. Still, I'm glad to have this model over the model 65 for output reasons.

Received a MS40W. It has two out puts, 12V and 15V. This unit doesn't have a output meter. It has LED's to indicate the output, but they are labled in Chinese as is the booklet. Too early to tell if I made a good buy.

i bought this generator hoping to get a type 50 like the others. Don't hol your breath they arent shipping anymore! This is a generator that is out of date and you cannot find the radios for anywhere. I hope to be able to tear into this and find some sort of a way to convert these 4 pin connectors which you can't even find anywhere on the web, to something able to safely tranfer a load. Wish me luck.

I received a model 50, dated 1981. This unit puts out 24 volts at 2 amps and is not the model 65 advertised. It arrived in perfect condition and is 50% less in price than others being offered. I have charged all kinds of batteries from 1.5 volt to 24 volt - all you have to do is adjust the cranking speed to match the battery. No need to build voltage converters. Thanks to the built in current meter function, you can monitor the charge current and not damage the generator or the battery. This is a great deal!

Like another guy that gave a review, I received a Type 50 also and got almost 27 vdc with almost no effort cranking. This is a great portable generator. Great for camping trips or emergency back up in running low voltage lights. This was one of the two items I bought from CTD in my first ever purchase from them. I am very please with both items.

it works grate to charge up a battery or run a radio when hunting best one i have ever used and own

I just received mine and it's set up for 2 amps at 24vdc and 1.5 amps at 30vdc. Excellent.

Well day two is better than what I first expected. After careful examination of my generator I found out I won the crap shoot. All of my labels on the generator show "50". The manual shows "50". The VA meter goes to 50V/2A. I cranked it up and put a DVM on the output cable and got 25VDC easy as pie. So I guess if you're lucky you'll get a type "50" like I did. Otherwise you'll get the 65 and have to modify it. I definately got what I paid for and then some. Thanks to Cheaper Than Dirt for an exceptional deal. Over the weekend I'll post some pictures and scans of what I have. Check mbodesign.com for details. This is a very cool generator and I'm going to put it to good use.

What a deal. It comes right from the surplus stores all packed up nice and neat in a wooden crate. Inside three packages all sealed nice and tight in good wrapping paper. Inside of that sealed again in waxed paper and I mean sealed. Then good sturdy cardboard boxes. All the goodies are there for anyone who knows what they are. The Chinese manual has a parts list and a schematic for an accessory PCB with the PRINT for the PCB included as well. It even has the major parts you will need to build the PCB. All the transistors and diodes are there. You can modify your unit with these to get your output power up to specs. I've taken pictures of mine and will post them on my website. mbodesign.com. Maybe I got lucky and got more than some people get when they order one. But I am for sure very pleased with what I got. It was wrapped so nicely that I might get another one just to keep it wrapped and prepared. It even comes with two cans of grease!

This generator will produce 50 watts, but it needs slight surgery to do so. There are at least two basic models, the 50 and the 65. The 65 was made for a Chinese clone of the post-WWII GRC-9 set, and as such delivers 6.3 volts for tube filaments, and 400+ VDC for the B+ voltage. The model 50 generator uses a three phase alternator along with six dioded to produce 24VDC @ 2A, or proportionately more voltage at lighter loading for battery charging. Externally, these units look identical, but are indeed different. The good news is that SOME of the model 65 generators used a transformer to step the low voltage three phase up to high voltage, and also stepped it dow for the filaments. These particular units can be modified by removing the tranformer and adding six diodes, effectively making it a model 50. There was, at one time, instructions on the web for doing this. Good Luck!

This product is well worth the money but doesn't come close to generating 50 watts as the best I can get is 10 watts. I get 6.3 volts and 430 volts from it and there is a schematic inside the box. I consider it fully worth the money but it's not what I thought it was.
