RE: [drakelist] 4 line blue filters
Please ask away. many of us also learn something as well.

If this forum is not for encouraging new folks in their Drake endeavors, then it serves no purpose. I, for one, gladly share what little I know, and DON'T keep score how many times a question has been asked. There are many of us who will help, and not chastise you for asking. Carry on!! If there gets to be too much email on a somewhat dead list sometimes, I am sure Thom is fully capable of telling us to slow it down, we don't need any reflector police doing so. 73, Don, WB5HAK
Re: [drakelist] TR4 wouldn't load
To the group all who offered assistance I did get it to load up about 1:30 AM this morning Garey Barrell [EMAIL PROTECTED] Hi Garey, Yep all of the filiments on the 6GJ5's were working as I advised, and you accepted as fact. Did get to the problem, my procedures and the antenna relay. Two clean out rounds later with the antenna relay got it (it had already had one) ...had to do a bit of tweaking too. Open frame, little plastic cover that clips on RF choke in the way, and I noted it needed a new SO239 so it got a lot of things done. Right now output is about 120 W but I am probably doing it wrong. Gotta find a local Elmer with Drake experience to go through the tune up procedures with me..until I can get it correct.

Re: [drakelist] TR4 wouldn't load
If the statement below is correct, that may be part of the problem. The TR4 having 6GJ5 transmit tubes could be your first real problem.The transceiver uses the 6JB6 tube for final tubes, or the 12 volt version in the very old TR4's and TR3's. There is a tendency because of cost and availability to use like replacement tubes, but doing so brings other problems to the table. I have experimented with several so-called 6JB6 replacement tubes, and have found there are no replacement tubes.Granted some substitutes work better than others but none performed well across all the bands as compared to using the 6JB6 tube. Many of the side effects of using substitute tubes include erratic tuning, max output not at resonant plate current dip, neutralization issues on the higher bands, filament string current unbalance, and the list goes on and on.The bottom line the substitute tubes will give you problems, and typically they get worse the higher in frequency you go. If your pulling out your hair fighting a problem like this, just make sure the problem is not being generated by using the wrong tube.

Re: [drakelist] 4 line blue filters
Ron Wagner [EMAIL PROTECTED] made an utterance to the drakelist gang -- I guess my statements were misunderstood as a flame to Carey. They were in fact defending his asking the question. I think a look on the web is prudent, but you can never know if the data is actually good, hence you ask here. As for the link statement, it was only meant to allow everyone to know that it does in fact work as of last night. 73, Ron On Wed, 7 Nov 2007, Carey Lockhart wrote: well i am the one who started this thread. and sorry for that i am. and i did not ask where to get the materials. i asked for the call or the web address of the man who sells the filters that more resemble the originals. now i am two months new to drakes and drake collecting. i joined this list in search of knowledge and technical assistance. there are collectors here that have gone thru all of the googling searching trying and still rely on experience in the end. i simply asked them to share. apparently was wrong about the use of this list. i did not know what kind of material it was, what its name is, that it was sold my FILM LIGHTING COMPANIES. who would have guessed film = radio. i still didnt get the info i needed but now i have several sources for material to make my own if i so decide. so 73's Carey Lockhart, KC5GTT [EMAIL PROTECTED] www.kc5gtt.com On Nov 7, 2007, at 6:32 PM, Ron Wagner wrote: Ron Wagner [EMAIL PROTECTED] made an utterance to the drakelist gang -- Not a flame, but rather an observation.

And unless you follow this list and know the players you never know if what you read on a site is from someone who has a clue or not. As for the archive link on zerobeat, it works for me.

Re: [drakelist] TR4 wouldn't load
Garey Barrell [EMAIL PROTECTED] made an utterance to the drakelist gang -- Ron - The 6GJ5 is the ONE substitute that I have found to work just fine in all the four series transmitters. It is an _identical_ tube to the 6JB6 with the single exception of the suppressor grid being tied internally to the cathode in the GJ, while the suppressor grid is brought out to Pin 8 in the JB. Pin 8 is hardwired to ground in all the Drake transmitters, while the cathode is at RF ground and DC ground via the 2 ohm meter shunt resistor. Since the Drake transmitters are Class AB1, grounded cathode finals, there is absolutely no effect on operation of the final stages. The same caveats about brands apply, i.e., some brands will NOT neutralize without modification, but otherwise the GJ works just fine. 73, Garey - K4OAH St Charles, IL Drake 2-B, 4-B C-Line Service Supplement CDs www.k4oah.com [EMAIL PROTECTED] wrote: If the statement below is correct, that may be part of the problem.
