Hello Steve, What is the problem you are having with your Alpha 9500? Are you getting an error number? If so what? Any additional information that comes to your mind? 73, Bruce, W8HW == Whats the lat
In one way or another... Yes- True Like a MD said one time, all death comes from lack of oxygen to the brain. One student ask what if an explosion happen and the person was blown into a million parts
Hello Cathy, I repair amplifiers and have seen this before. I can only guess that the Door Knob cap went bad and someone replaced it with the orange cap just to its left. Doorknob cap are often repla
Bill, You should stop being the blind one. I noticed that you edited (snipped) my response to your advantage. That is dishonest and deceptive. My FULL statement was correct and you are blind to it. -
That is funny... In this long thread, everyone answered every question EXCEPT the question that was asked. That is funny. --Original Message-- From: Mike Waters Sent: Friday, December 02, 2016 11:52
Cathy, Well put... I could not agree with you more... I have Ameritron AL1500 Gives me full (plus) power and Kenwood TL922 (1400 watts). Yes both are manual tune, but both work so great. I have repai
Every one is talking about Obsolescence of tubes. The problem is the other way around. The truth of the mater Solid State finals often stop being produced in around 18 months. After that you can get
Mike is correct. I have used 27 inch of #18 wire on 3-500 tubes many times and got voltage down to 4.97 volts for each tube. The wire is just one big resistor and gets warm, but works fine. The life
Caution... Yes you can but... In the case of 3-500 tubes each diode would dissipate 8.5 watts (14 amp * .6v) so for Continues use, you would need 15 watt or better yet 25 watt diodes and that would b
Yes I remember and you are so correct. Thank you Rodger for putting it so well. 73, Bruce, W8HW == --Original Message-- From: Roger (K8RI) Sent: Monday, January 02, 2017 06:20 To: amps@contesting.com
Bill you are so correct, it would be a sad day if the homebrew side was squeezed out. It was a sad day when companies like Heathkit disappeared. Now we hear complaints that someone purchased a box, p
Hello Cathy, The answer is increased "RESTING" plate current in high voltage position. Resting plate current does NOT produce any RF, so it becomes 100% heat and 0% RF. The plates dissipate extra pow
You got that right, the $325.00 price is just wrong. Pay no more than $2-15 at Hamfest. I saw all sizes shapes and spec at Orlando. Use ohms law to shunt it for current reading, resister dived it for
Hello Cathy, Greetings from sunny south Florida. Thank you for your email. The cost of building this amp was only around $2k, it was a love of building. I am thinking about tearing it down and buildi
Hello Charlie, Sure Charlie, glad to help. Bands are 6-160 Meters. I am including some pictures for you. As you can see, I have not done the lettering yet. I went with the 2.4 KW amp from the Russian
In my 40 + years in transmitter repair, I have repaired hundreds of Solid State amplifiers and less than that tube amplifiers. Most people have the idea of tube Obsolescence is a problem and that is
Yes it has output from 160 through 6 Meters at the same time. By "same time" I mean while inputting a single signal, the white noise is covering all bands at the same time. And no tuning. As far as t
That is just not true at all. The Cw bands are hopping all of the time. I spend most of my time on CW and have a "rag chew" almost every night plus several shorter qso. I guess you don't do much Cw a
The CW bands are hopping all of the time. I spend most of my time on CW and have a "rag chew" almost every night plus several shorter qso. Again, CW is jamming with lots of QSO going on at all times.
Hello Jim, Good to hear from you. Sorry that you don't hear them. All I can say is I hear and work them. I am looking at a bunch now. Signals from the bottom up to around 50 KHz up and more. DX gener
