Good day to everyone. I just signed onto the list and would like to know if it ok to list RF amplifier parts for sale on this list? In addition to fooling around with old ham radios, I have also acqu
I've got a large enclosed relay rack cabinet that I really need to get out of the garage. Dimensions are: 47" tall, 22" wide, 19" deep. Panel space is 19" wide, 42" tall and about 17" deep. Grey crac
Thanks to everyone who expressed an interest in the cabinet. It has been sold to a ham down in North Carolina. 73 Bob, WA2CKY _______________________________________________ Amps mailing list Amps@co
Just a bit of a positive word here about QST and ARRL - if you are looking for technical content, don't forget QEX. The technical content is quite a bit higher in that adjunct magazine. Everytime I t
Did some poking around on Google ('EIMAC application bulletins') and did find that the EIMAC web site (www.cpii.com/eimac/eiapps.htm) does have some of the old application notes available in *.pdf fo
My initial reaction was skepticism but the indicated input network is exactly what is indicated in the Eimac data sheet for the 3-500Z. Good pdf copy of the 3-500Z is on this web site: http://www.rad
Peter, I would love to have a reprint or pdf file of that article! 73 Bob, WA2CKY _______________________________________________ Amps mailing list Amps@contesting.com http://lists.contesting.com/mai
Looking for a copy of a 3-part article by W6SAI entitled 'Linear Amplifier Design'. It was published in Ham Radio Magazine, June 1979 (page 12), July 1979 (page 34) and August 1979 (page 58). I got r
I think the BAMA main site has shifted servers, etc. This URL is working <http://bama.sbc.edu/> The mirror site is also a good bet. 73 Bob, WA2CKY I have never had any luck with the BAMA site. Below
In case anyone is interested, I was cleaning the basement today and found two of my original EIMAC application notes which I don't think are on the EIMAC web site. I am going to scan them into a pdf
Received copies of the Ham Radio articles from two great guys! Thank you both - another incredible response from the folks on these lists! 73 Bob, WA2CKY _____________________________________________
I am cleaning up a bit and have the following softcover books/application manuals (plus others TBD) which I would like to see go to somebody who might enjoy them. These plus a few other one's I have
The URL got chopped off: try www.alltronics.com 73 Bob, WA2CKY Seems someone was asking about a source for Isolation transforms on here in the last week or so... Check out this link: http://www.alltr
Another factor that might come into play here is the gain and feedback capacity. Both have a big role in determining the actual input impedance of an amplifier. That is, the input impedance is a comb
Ok, how about pulling all the treads together on this topic and both summarize and visualize an ideal filament supply - 1. Regulated DC voltage - low noise 2. Voltage output settable to accommodate d
Finally getting back to the basement cleanout and I am starting on those high power amplifiers I mentioned sometime ago. First and easiest item to sell and ship is a very, very clean EIMAC 4-1000A tu
More basement cleaning and recognition of things I will probably never use. I picked this RF load up several years ago and have never used it. Again I thought I would offer it here on the list before
The figures I remember on semiconductor temperature and reliability go something like this: 1. Typical lifetime at junction temperature of 200 degC is somewhere in 10,000 hour range 2. Lifetime doubl
Thanks to all of you who sent emails giving me some pointers on the value of the 4-1000A I listed for sale a couple of days ago. I'll incorporate all of those comments when I list the tube for sale.
Just had a thought on this subject - there are 'whole' house ac line surge protectors - industrial type - that are intended to be connected directly on the side of the the house breaker box. One sour
