**The SB-200 makes a pretty good 6 meter amp using the 572B tubes. Not ALL 572B tubes work well on 6 meters, but some do. My suggestion...Sell your 2100B get an SB-200. I tried a 2100B on 6 and had a
I DO NOT suggest being an authority on this subject about transformers, but in my experience over the years with them, it sounds to me that 30 pounds for a 1.5ACCS transformer is very light weight. S
It is quite a process to accomplish this "piece meal" You need a new bandswitch, wafer, and input wafer as well as a 10 meter input coil. Its a lot of work to do the conversion. The easy way out is t
Tim, if you are getting more idle current than is specified then your zener diode has gone. I don't recall if they use that electronic baising on that amp, but if they do, whatever sets the bias volt
Hi Bill, I once used an MFJ 16010 mini-tuner in front of my Swan Mark 1 amplifier as a tuned input. When not in line the exciter (Yeasu FT-847) would fold back in power to about 50 watts. I would the
TIM, the 120volts for the fan when the amp is plugged in for 240v operation is derived from one leg of the 120 from the wall socket and the neutral is derived from the center tap of the dual primary
Hi Bill, Did you try retuning the coil after you replaced the caps? If you did, maybe the coil material cracked? At any rate, I would try adjusting the coil for least SWR and if that does not work yo
SO THEY REPLACE THE CHOKES OR THE MICA CAPS THAT ARE ALREADY THERE? _______________________________________________ Amps mailing list Amps@contesting.com http://lists.contesting.com/mailman/listinfo/
DO YOU HAVE ANY PARASITIC SUPPRESSORS? SOUNDS LIKE THE AMP IS OSCILLATING. COULD BE SOMETHING WITH THE INPUT TOO. _______________________________________________ Amps mailing list Amps@contesting.com
I was going to mention that from the beginning. Unfortunately, many do NOT know the correct way to load an amplifier especially if its your first one you have owned. Good Luck _______________________
Mr. Measures, you certainly have a keen sense of humor! You missed your calling. Have Phun. :-) 73 Louie _______________________________________________ Amps mailing list Amps@contesting.com http://l
You supply every little information to make diagnosis, however, I think perhaps you have a problem with the line voltage getting to the power transformer from the "step start" relay. There are numero
Hello, I would try disconnecting the HV AC from the transformer to the PS board, so that the only thing connected to the line voltage is the filament transformer, and the HV transformer. Protect the
I cannot speak for the longevity of the RF parts 3-500ZG or the Taylors sold by RF parts, BUT I can tell you that they work flawlessly on 6 meters up to the 1300 watts I get out of them on my convers
Hi George, It always amazed me how the CM-2 input matching "black box" was sold to match the input of all the Dentron amps that did not have a tuned input circuit. I do not know anything about it, bu
Just for the record fellas, I had converted an AL-1500 to 6 meters (50mhz) and with 100 watts drive, I was getting 2300 watts output without exceeding any of the the tube max ratings. Its one hell of
Hi Darrell, I have owned 2 of those amps. You can't own that amp and not be an amp Guru. The amp is lacking BIG TIME in a lot of areas. First off, the cooling system is a joke and that is why it over
Possibly because regular soldering can melt under the heat of the circulating tank circuit current. A mechanical connection is better for this area, there is nothing that can melt. I HAVE SEEN IT HAP
Check to see if your grid meter shunt resistor is opened. It just might be! Cheers Louie _______________________________________________ Amps mailing list Amps@contesting.com http://lists.contesting.
