Hi all, stupid Yahoo apparently caused me to be bounced from the list, glad to be back in. Just picked up a Fluke 207 (no suffix?) VLF receiver/comparator, and would like to do some reading on it before putting any time or money into a rebuild.  From my recent 332B overhaul, every single electrolytic in this thing will be replaced if it's going to see active duty again.  I suspect it may possibly be a better unit than my HP 117A, which has a really messed up amplifier requiring replacement or a parts donor.  There doesn't seem to be a whole lot of info about this 207 online, hoping perhaps someone has a digital copy of the manual which could be emailed?  This one is also missing the top and bottom covers, if anybody happens to have a parts set! Regards, Chris  Sent from my SMRTphone

Chris I know the 207 well. I have one up and operating just fine. Several items they do not tolerate the new WWVB bpsk signal at all the same for your 117. Though the 117 at least seem to do semi ok. Amazingly, it really should not. I just had to re-cap all the small electrolytics all of them were seriously off and low in value. Thats after many years of service. For me 10 years and since its 1970s technology some place else. The caps really were not a huge cost but a lot of work to change them. The 207 actually is a better receiver then the 117 so its worth it. I also replaced the fried audio amp with a modern chip design and disabled the phase accumulator. It will drive you nuts with the click. Bad news on the manual though I have one and it really can not be copied. Its whats called a blue line the prints are large and multi page in size. Still smells like ammonia. Its becoming very delicate with age. On all of my wwvb receivers I use cheatn d-psk-r to get rid of the bpsk and that allows them to work like they used to. On the 117 whats up with the rf stage? I just had to re-tube and recap mine. Cathode bypass. Wasn't that hard. There is a guy near boston that has really good NOS and at reasonable prices. Not sure if some one hacked your unit or perhaps lightning. But the TRF is rock solid with great gain. HP nice.

Dave like normal amazing that you have it. Chris Daves manuals are as good as its going to get. I am amazed. The box on the right as two mixing boards and one broad band filetr and yes there a slots with nothing in. They were intended for special frequencies like omega or NAA.... So most likely you are fine. You can always snap a pix. With respect to the 117 I have two and like them both. I sort have far to many wwvb things.
