[drakelist] TR3-4-4c etc idiotic question
Hi all, TR3-4-4c etc The sliding plastic freq plate, w/ little red knob. A wave washer goes over the red knob. I am assuming the washer goes between the clear plastic and the aluminum front cover ? With the bow on the washer in or out? I have tried in and the twin edges hang on the opening in the (alum) front faceplate, and literally won't let it move. I never had the washer and now I do ...but.Carl **Check out AOL's list of 2007's hottest products. (http://money.aol.com/special/hot-products-2007?NCID=aoltop000301)
[drakelist] bulbs
Hi All ?I found that I had several sets of led conversions for my now gone tr-7. I have given all my books and papers with the tr-7,so I can't look up anything. What was the voltage on the dial lamps and meter lamp on the tr-7? and was it ac or dc feed. Iam using the extra bulbs I have left,...led... in a ten tec tuner ,they fit just great. This info would sure help ,before I apply the wrong voltage and cook the leds. thanks dale wt4t More new features than ever.

Re: [drakelist] Power tubes for T-4XB-C, TR-4C
looks like I found a TR4 matched set of 6JB6s in the garage that I got back in '99, looks like from WB2LHP. Two Sylvania's and an RCA. Slips of paper for each, two are marked 109, one is marked 110. Those numbers are exactly what ? What is the typical variation seen among NON-matched 6JB6's ? What bad stuff might one see when not using matched sets ?

[drakelist] Drake AC4R upgrade in Jan 2008 QST
Boys and girls.. After much hair pulling and emails between the arrl, last year I convinced them there is enough interest in the old drake to warrant publishing the article about fixing the old ac4 supplies. It took several rewrites to please the editors: they did not want it to read like a infomercial So now it's going to appear in the January 2008 issue of QST. So, that being said, if you like the article and want to see more stuff on older radios, (and not just from me) how about popping by the arrl.org web site and voting on the article? here's a link http://www.arrl.org/members-only/qstvote.html?pidx=0 I don't now for sure, but you may have to be a member of the arrl to get to this link. If you don't care for the article, that's cool too! But the bottom line is this. They print what people read!

[drakelist] R-4B alignment question
Hello, I'm in the process of going through a R-4B. Have already recapped the paper and electrolytic caps and changed out of tolerance resistors. Now it is working great from 40 meters and up. But, I have low sensitivity on 80 meters and almost no Receive on 160. The Cal barely moves the S-Meter on 80 and it doesn't budge on 160. I'm going to do a complete alignment. After looking through the manual, the section on aligning the Antenna, RF and Injection circuits, call for a 12.6 MHZ crystal. Is there a work around for the 12.6 Mhz crystal? I don't have one. Thank you in advance. Best, DW Holtman WB7SSN
Re: [drakelist] Power tubes for T-4XB-C, TR-4C
Garey Barrell [EMAIL PROTECTED] made an utterance to the drakelist gang -- Chuck - Those numbers are about what you see on a TV-7/D tester and are equivalent to transconductance, or gain of the tubes. The procedure used by Drake was to plug them into a test set that duplicated the circuit in the T-4X final, set the bias for 35 mA, and then plug in one at a time however many they wanted to test/match. Their numbers, not related to any quantitative measurement, were typically in the 35 - 40 range and were marked on the top of each tube with a felt marker. Neither method has any direct relationship to their performance at RF! Matched tubes are not really _necessary_, but mismatched tubes can have 3rd order distortion products considerably higher than a matched set. This can vary from a few percent up to tens of percent depending upon the degree of mismatch. If you consider a pair of tubes in parallel, say that one tube draws 30 mA at a given bias voltage, and the other draws 40 mA. The plate meter shows 70 mA total, but one tube is considerably different from the other. When drive is applied, one tube will also draw more plate current than the other, so one tube may be providing 60W of the output and the other 70W. Distortion increases rapidly when tubes are driven past the optimum, which Drake measured at 175 mA per tube. So if one tube is drawing 150 mA and the other is drawing the other 190 mA, distortion can be pretty bad! Your nearest neighbor ham probably won't appreciate it.. Of course it gets MUCH worse if you are driving an amp, since the amp contributes its own distortion on top of that from the transmitter. This tends to widen your circle of fans! :-) Mixing brands of tubes is also not prudent, even if matched DC wise, because different internal construction can make it difficult to neutralize the final over all bands. It works ok a lot of the time, but if the neutralization seems hard to optimize, or better on one band than another, this could be the cause. Drake used both Sylvania and RCA, but always paired, or tripleted(?) them by brand. Sylvania was the only sweep tube manufacturer that published data for linear RF use. 73, Garey - K4OAH Glen Allen, VA Drake 2-B, 4-B C-Line Service Supplement CDs www.k4oah.com Chuck Grandgent wrote: looks like I found a TR4 matched set of 6JB6s in the garage that I got back in '99, looks like from WB2LHP.

Re: [drakelist] R-4B alignment question
DW Holtman [EMAIL PROTECTED] made an utterance to the drakelist gang -- Agree, Thank you for the information. It makes perfect sense, since there is only 5 crystal slots, not counting the accessory slots. This receiver came out of a TR-44B and mates to a T-4B that comes with a built in speaker, but no PTO. Kind of interesting. I like the way they stack together, and the door to add accessory crystals. However, I think I think I would rather have a Transmitter with a PTO. Might get one soon, and put it in the cabinet. I was struggling with the transmitter power out, then discovered that there was no injection voltage out of the Receiver. There is a strong injection signal to the cathode of V2, so there is not much left between the cathode of V2 and the RCA connector. Thought I would do a complete alignment and get the receiver working well before going on to the transmitter. Thank you again for your as usual great information.

Re: [drakelist] Power tubes for T-4XB-C, TR-4C
[EMAIL PROTECTED] made an utterance to the drakelist gang -- Chuck, Those are likely emission numbers from a tube tester. If the tubes are not perfectly matched, all sorts of nasty things happen including misalignment of the planets, contamination of all known water sources, and the atmosphere will become completely toxic. So you don't want to go there. But for those that are mavericks, you can use mismatched tubes in the transmitters, transcievers, and linears. But there is a limit as to how much mismatch can be tolerated. There are a lot of old wives' tales that are founded in part from back in the 20s and 30s where push-pull circuits were common in RF as well as audio. Mismatching was more critical with those types of circuits. But in modern applications, where the tubes are in parallel there are three issues to consider, (1) power dissipation, (2) neutralization, and (3) intermod. As long as the power dissipation on any single tube does not exceed manufacturer's specs, you won't stress any of the tubes. As to neutralization, well, it depends and with different tubes you have different interelectrode capacitance, in addition to different emission; does it matter, you don't know unless you try. As to intermod, I've done a limited number of tests with a T4XC and L4B. In each case, one brand new tube was mated with a a well used tube. No observable indications of intermod etc. were observed by my local receiver and some hams several hundred miles away. To know for sure, one would need a spectrum analyzer. To each their own. I think the topic of matching is grossly exaggerated. Yet, there are cases where the mismatch is just too great and problems will occur, I just haven't experienced them. Guess I've been lucky so it is best not to use mismatched tubes and thus destroy all life forms as we now know them. 73, EvanBRBRBR**BRCheck out AOL's list of 2007's hottest products.BR(http://money.aol.com/special/hot-products-2007?NCID=aoltop000301)/HTML -- Submissions:[EMAIL PROTECTED] Unsubscribe:[EMAIL PROTECTED] - unsubscribe drakelist in body Hopelessly Lost:[EMAIL PROTECTED] - help in body of message Zerobeat Web Page: www.zerobeat.net - sponsored by www.tlchost.net --
