Here is where the confusion arises: The chassis lettering and schematic for tubes V4, V5, V11 and both agree and are respectively: 6EJ7, 6BA6, 6BZ6. Note: the schematic has V5 and V11 with a hand lettered 6 in front of 6BA6 and 6BZ6 versus all other tubes which have stencil guided lettering. The Manual's Voltage Reference chart and Tube List for V4, V5 and V11 are: 6EJ7, 12BA6, 12BZ6 The Manual's Block Diagram shows V4 as 6HS6 I'm not sure what's supposed to be right, though I have a tendency to believe the chassis lettering and schematic. The manual is internally inconsistent, and doesn't agree with the physical hardware or schematic. I probably can take out V5 and V11 and measure the filament voltage present to see if it really is set up for a 6 or 12 volt tube in those sockets. I found some correspondence between the original owner, whom I purchased the unit from, and the factory regarding a technical problem. The factory rep wasn't sure in solving a problem whether the former owner needed a 6BZ6 or a 12BZ6 so he sent him one of each. Apparently the factory didn't know either! Was there some changeover for different serial number ranges, between various tube types or what, and what is the best way to tell which tubes really belong in the circuits?

I stumbled on the fix myself the first time when recalling my radio tech friend's cure for many Yaesu FT-101 problems was pulling the boards and cleaning the contacts with a common eraser. I've had this problem as well, mostly manifested as an annoying intermittent with one of the DR7 connections. I think I have finally resolved it with sparing application of DeOxit to the contacts. Don't use the spray, I got the applicator bottle with the needle tip. My new R7A had a problem of a little different sort - one of the pins on the parent board had a small blob of solder right at the very end, which had slightly deformed the socket contact when the board was inserted. I suspect this was a very rare occurence, but may be something to watch for. After I removed the solder from the end of the pin, I unsoldered the receptacle from the circuit board and was able to remove the contact from the connector shell and re-form it into shape. It's working fine now. One other problem of this nature is the solder on the long pins of the DR-7. There is quite a bit of stress on these soft-soldered connections, and they are subject to the solder cracking. This is not always visible so reflowing these connections is a good preventative and/or possible repair if temperature or mechanical pressure causes DR-7 misbehavior. 73, Garey - K4OAH Glen Allen, VA Drake 2-B, 4-B, C-Line TR-4/C Service Supplement CDs www.k4oah.com ___ Drakelist mailing list Drakelist@zerobeat.net http://mailman.zerobeat.net/mailman/listinfo/drakelist **Make your life easier with all your friends, email, and favorite sites in one place.

[drakelist] T-4XC problem on CW
I have a T-4XC that works fine on SSB but when I switch to CW and key the transmitter, It has full or a lot of drive applied and the gain control has no effect or control over the drive. Has anyone out there run into this before? I thought I would check before I start looking for the problem. Thanks, Terry W8NJR **Planning your summer road trip? Check out AOL Travel Guides.

Re: [drakelist] T-4XC problem on CW
OK Garey the ground is there. The pots both check about 520K ohms across the full windings and checking at the center terminal, the back pot checks 0-520K ohms. The front pot nearest the panel checks 0-15K ohms across the full range. I must have a problem somewhere else. Terry, W8NJR In a message dated 4/4/2008 11:11:24 A.M.

[drakelist] TR-4C working again!
To all, thanks for the help given me on the drakelist here. Garey's suggestion to short the filters and listen to the calibrate signal on both sidebands did the trick. Shorting the filter got the rf flowing and listening to the calibrate signal on both sidebands told me the 9 mhz signal was off frequency a little. So I aligned the 9 mhz signal so the calibrate signal sounded the same in both sidebands and after that I could take the shorting lead off the filters and the signal passed thru OK. After that came a complete alignment job. The radio now has 150+ watts output on 80, 40, and 20 meters and reduced output on 15 meters. The receiver sounds great! I still don't have anything out on ten meters but I will get to that soon. I just finished a QSO on 20m with it and the report was good. So thanks to all who helped and to those who let me monopolize the list a bit yesterday while searching for answers. I would still be looking without the help I received. 73, Terry W8NJR **Create a Home Theater Like the Pros. Watch the video on AOL Home.

Re: [drakelist] TR-4C working again!
Thanks Lee. It is fun to get them going again. This one was a basket case when I got it with multiple problems. Someone was in it adjusting every can the wrong way and it had numerous bad tubes in it. Anyway's, it is fun for a old retired mechanical engineer to be able to save the radio and get it going. New radios don't sound near as good as these old Drakes! 73 and thanks, Terry W8NJR In a message dated 4/1/2008 7:24:05 P.M. Eastern Daylight Time, [EMAIL PROTECTED] writes: Terry, Congrats man...

You are right Lee. I sold my Orion because all I used were the Drakes. The Orion was a nice radio but not the pleasure to listen to and operate like the Drakes.

[drakelist] TR-4C
I am still working on my TR-4C. I now have the filter problem fixed and in fact have the correct signal going all the way to the 12BY7 driver tube. I do not have any signal coming out of the driver to the finals. The tube is good and I have substituted another with no change. The voltages all check good on the 12BY7 except for pin 8. It has the full 250 volts on it so no grid current is flowing there. What might cause this? Has any one out there run into this problem before and maybe could tell me where I should look for the problem. As always any help would be appreciated.

First thing comes to mind is that the Carrier oscillator isn't running, and you are tuning to the second harmonic of the PTO. On 20M you should have 9.000 MHz from the Car Osc. mixed with the PTO at say 5.200 MHz to produce a signal at 14.200 MHz.

Re: [drakelist] TR-4C
OK checking at the center pot terminal on the carrier balance control, my freq meter flickers between 8999 and 9000 khz. When I go to T then it flickers between 9000 and 9001 khz.
