Can someone give me the voltage and current specs on the 8 henry power supply choke in the original version AC-1? Also, how critical is the 8 henry value? ...
My b+ voltage is giving me only 280 volts no load due to the transformer I am using....should the value of the resistor to the grid be changed or is everthing...
Choke is not critical. I think subsequent versions did away with the choke. The GB-1 version uses cap input, nothing else. Runs fine and last a long time. ...
I will check it out--thanks ... From: C E <catman351@...> Subject: Re: [amecoac1] Voltage question To: amecoac1@yahoogroups.com Date: Saturday, June 6,...
Hello AC-1 builders. Maybe you know this all ready but I post it anyway. I did search for a chassis for start building a AC-1 but I did not find any. But I...
Hi Cal, What does "recovered" mean ? ....are they still the 2" chassis ? I see the group is still going strong. I still have not built the GB-2 or GB-3, or...
Opposite of "misplaced" or "missing." I finally found them or "recovered" them. Sorry about the confusing. Say, got any more decals? I may need 20 of...
Folks: Along the lines of the AC-1, I'm considering remaining a version of that Meissner 6V6 transmitter. The footprint will be the same as the GB-1,...
I am always looking for a new project . However Bud , B&W , etc . coil stock tend to be rather expensive these days . I would be interested in seeing a...
Hi Charlie, Believe it or not, the original AC-1 circuit meets current FCC spectral purity requirements. I was quite surprised when I measured mine. See the...
Found this while watching another video about homebrew radio: http://www.youtube.com/watch?v=6EuMDQu9DH8&feature=related Jack WA6KYO has a nice station...
Here's a link to John's web pages: http://electronicsusa.com/wa6kyoshack.html The HB transmitter is a 35 Watt 6146, not a 6DQ6 as I had guessed. 73.......Steve...
This should not be a surprise. The tube-type transmitters of all types tend to relatively "clean" in terms of spectral purity in comparison to solid-state...
I agree wholeheartedly. I guess I should've said that I wasn't surprised that it was clean, just surprised that it met current FCC requirements which, at...
I know the pi-net is good at this type of rejecton. What about the parallel tuned network? Thanks. Cal. ... From: sigcom1 <sigcom@...> Subject: [amecoac1]...
Folks: I don't know if you have been perusing through the 'bay, but Conrad Warren, W7WLM, produces NEW 5 pin coils for your BA transmitters. These are the...
Send us a few more details. 1. Are you loading it into a dummy load ? 2. What is your key up and key down B+ voltage ? 3. Did you use the 6X5 / 6V6 tubes ? 5....
I built the clone...looks great but not working correctly. I do not have a wattmeter that reads low enough to get a reading but it is dimly lighting the...
Not the best transformer, possibly need a larger filter cap, and/or your plate choke uses too thin of wire or cathode choke in keying line too small). Some...
The plate of the 6V6 has a large amplitude R.F. signal present.... or it should. You're not going to make an accurate DC measurement at this point with a VOM....
With the rig powered down and the HV blead down, measure the resistance of your RF Chokes. The chokes in my AC-1 measure 60 Ohms. I would say that if yours...
I stripped out the components going to the grid and plate from the power supply and redid the wiring a little different. Whatever I did it works now. I am...
Jon, That's great news, congratulations! 6 Watts is very good output at that B+ Voltage. Sounds like you did a good job. 73.......Steve Smith WB6TNL...
