This kit is amazing. I have done a bit of soldering in the past and can kinda sorta ;) read schematics.

I was able to put this kit together and plug it in and have it work - the first time (I was not expecting that for being such a novice). The directions were amazing! I added a headphone jack to it so I could more easily plug in mp3 players, etc. I can now use my ancient AM radios to listen to my mp3 player. Just so cool!

Hi,
After a long time I have again occupied with my k-488.
Rolf from Switzerland had wondered about the low power at the given 135v anode voltage.
This was also expressed by an American hobbyist in the "antique electronic supply forum", unfortunately there were no changes.
Rolf had then an anode voltage of 27v suggested, so the transmitter worked so synonymous.
The same I have also tried and I have come to the same result.
Comically only, the other Nachbauer with the 135v good results have reached.
I have now found that a much larger modulation is required for the 135v.
Nevertheless I will stay with the lower anode voltage, it works so satisfactorily.

Pretty cool. I built my own enclosure for it and I fashioned a sheet metal shield to go around the tube and connect to ground. It helped me because I had a glass envelope tube with mine. It's got enough out put to listen around the house. I suggest wiring in a power switch. Mine didn't come with one.

I put the kit together in a few hours. The instructions were very straight forward and easy to follow. Following what someone else mentioned their review, I also added a 220pF capacitor in parallel with C2 to bring the frequency down to about 625 kHz. I needed a bit more antenna to get a better signal, but I'm thrilled with the results!

Another fun kit. I have this hooked to a small preamp that runs off either a computer audio out, a CD player, or an MP3 player, but most of the time, I play old radio shows that are broadcast online. These are the real deal, replays of shows from the golden age of radio. Badge 714, predecessor to Dragnet, Gunsmoke, the radio show, The Shadow, and stuff like that. Amos & Andy could be considered racist & not PC these days. I can also play old Lindeyhop Jazz, Big Band or old Gand Ol' Opry. Easy fun little kit, and my programming can be contemporary with the age of the radios! Let's face it, Queen La Tifa don't belong on a Collins farm radio, or a Philco cathedral set! Ernest Tubb?, or The Monroe Brothers? Duke Ellington? Cab Calloway? Scott Joplin? That's different! That's the good stuff, especially those old black jazz & ragtime masters of musical magic!

I bought this kit some time ago. I hooked it up to the tape output of my stereo receiver. I was able to play records, my iPod or whatever I wanted. The tape output was a perfect gain level to drive this thing

It's easy to assemble, but would be better if it had a pre-amp too.

Received my kit today really happy.
Opened the box checked off all the parts etc all there and accounted for, Oh by the way really nice packaging 10 out of 10 for that.
Any way had the kit up and running within a couple hours and it works really well.
I had to use a step down transformer until I source a 240 volt equivalent as power here is 240V but all went well.
I used a long Ariel wire just laid on the floor for now as where I live no neighbors for a long way and NO radio stations so no one to worry.
It actually worked with no Ariel but I wanted to hear it up the shed.
The Instructions where alright and easy to follow.
This was my first valve type build so rather happy it fired up first go.
Any way thanks to Antique Elec for having such a neat little kit which I was lucky enough to find.
The only down side to buying from the US is the postage cost, maybe something to look at in the future for all your international buyers which I am sure you have.
Kit difficulty is not that hard.
Quality of kit is good.(would have liked to see a glass version of the 12SA7, the nice red glow)
I'M happy and I guess that's all that matters.
Thank you

Nice kit. Quality parts. Built it in a couple of hours. Fun new toy to transmit stuff from the internet through my old radios. Works well with 1940s superhet and AK TRF radios. Like one of the other guys says adding a longer wire antenata...like 12" antenna wire makes a big difference. Gave it much more reach.
