Re: [drakelist] re TR7 PTO/troubleshooting in general
Dave, over the last few years I have repaired and refurbished many TR7 radios which drove the first article I wrote on the TR7. I have been collecting a lot of data on this subject and plan on writing follow-up articles in the future.In the meantime, if anyone has finished articles on repairing the TR7, I will make space available on the WB4HFN website to publish those. Ron / WB4HFN -- Original message -- From: David Chris Drake [EMAIL PROTECTED] To the list, Has anyone ever compiled a troubleshooting doc for the TR7?? I know there are a lot of bits and pieces out there and have downloaded and printed many of them for my files. The service manual is also imperative, as well as extender cards. This would be a good thing for us Drake lovers to have a TR7 specific guide. Particularly since these radios are now getting some age on them and components harder to find. I just bought my second TR7 in non-working condition and will begin restoration soon, so this is up front on my mind. Any comments would be welcome. Maybe Ron Baker could expand on his excellent inside the TR7 article on his website. Or all of us could contribute info and experiences to someone else who could compile and document?? It could then be posted on Ron's site for all to access. Or the more industrious could print a book or CD and offer for a fair price. As an example, I have a copy of the Swan Compendium, without which, restoring a swan is much more difficult. Common problems and common solutions. I think it was $25 back when it was available. Another example is the video that was produced some time back for the KWM2.!!

Re: [drakelist] re TR7 PTO/troubleshooting in general
Well, looks like I brought up a popular topic. Thats a good thing! I would suggest a repository of information, or simply said, a place where any of us can send information or links such that some Drake loving volunteer can compile the information and check for accuracy.This should be someone who has lots of experience with the 7 series. I think I have an idea, and will contact that person separately so as not to put him on the spot on the list. Until then, I'll likely need some help from you guys as I progress. And you'll here me more often on Sunday afternoons as well !!

[drakelist] TR7 Project
I began to disassemble my project TR7 this afternoon and heard something rattling around toward the front of the rig. As I kept disassembling, it finally fell out, well pieces of whatever it was fell out. The two pieces looked awfull familiar, but I just could'nt figure out where they came from. Then after looking over my service manual pictorials, I found it. The top pieces of T2101, part no 2512001, the transformer on the power supply board. I have not pulled the board yet, but does anyone have an idea of a source for this part?? Or do I look for a parted out rig's board? I'm satisfied it should be replacedlooks like it may have been a bit too hot. And, of course, some failure analysis will need to follow. Thanks, David Wd9cmd

Re: [drakelist] TR7 Project
Don, if you have one to offer up, I'd sure be gratefull. If you don't have one to spare, I'll likely start looking for another board thats been parted out. Parted out boards seem to be on ebay weekly, but I'd rather find the part to fix up what I have. I'm in no big hurry. I'll probably pull the pwr. supply board tomorrow and give it a better inspection. Sounds like we're getting some nasty weather coming, so I'll probably work out in my shop quite a bit. I need to continue disassembly and start cleaning contacts, and do further visual.
