I think that the Hickok 546 , Hickok 547 , Hickok 547A , and the Hickok 548 testers may use the same settings data as the TV-3 and TV-10 series testers. I'd like to verify this. I'd appreciate it if anyone that owns one, or has a manual, schematic, or settings data for the 546, 547, 547A, or the 548 would contact me.

TV-3 and TV-10 Series Tube Tester Data Settings Project
January 5, 2003
The current downloadable beta is .018
Please email me after you download and look at this thing and let me know what you think...
Due U wAnt 2 help pro0f reed? If so, drop me a note telling me which rollchart and/or manual you will be comparing my file to to check for errors and I'll send you a copy..
I've FINISHED typing in all of the data (01A to XXL) from the below listed source material. If you have any additional source material that I'm looking for (listed below) it's time to let me know. It's now time for some error checking. After that, I start adding additional settings data for tubes not listed in any of the Govt. publications.
I'm sitting at over 3000 lines of settings data typed in so far. I used the 1966 roll chart in my TV-10D/U as the "primary" source and added settings data from the documentation listed at the bottom of this page that I have access to. There is settings data for hundreds and hundreds of tubes that's scattered around in the various manuals etc. that's not on any of the roll charts. This will be one hell of a file when it's finished. I'm guessing that it will be larger than any of the other settings data files that I've done for the other models of testers as far as "coverage".
As best as I can tell, the May 1966 roll chart was either the last update or damn close to it. If you have a roll chart later than May of 1966, please email me.Also, if you have any manuals or supplements that are listed at the bottom of the page as "wanted" drop me a note.
If you want to spend some time proof reading, drop me an email telling me what data source you'll be using for comparison on your end along with a note on which part you'd like to proof read. I've learned a lot doing these projects and have found that I get the best response when I ask for on one "number" per person. As an example, all of the 1 volt tubes or all of the 5xxx numbered tubes, etc. At any rate, drop me a note and I'll attach a copy of the whole thing just in case you want to check more than 1 series of numbers. :-)
The current beta is 0.15 which covers all of the tube numbers from 01A to XXL. It is a zip archive containing an Excel file created with Office 2000. Info on the file format along with a link to a free reader for Win32 platforms is listed toward the bottom of this page.
I'd also like to thank the people that have taken the time to email me the contract info and SN off of their TV-3 and TV-10 series testers. It looks like there were a total of six contracts for the TV-3 series and a total of ten contracts for the TV-10 series. What we need know is more SN information to get an idea of just how many of them were built.
The data collection continues, but more is needed...please check the list below.
I have added what contract information that I've put together so far just below. Please drop me a note if you have any contract numbers not listed or any "high" or "low" serial numbers to add in order to help get an idea of just how many of the TV-3 and TV-10 series testers were built.
Well, it was a matter of time I guess. It looks like I have another project. :-)
I now have a TV-10D/U in my grubby little hands. I did a quick check and it appears to be basically functional. I had to replace the latches on the case and decided that while I had it apart that I'd go ahead and do a total check of all of the components, give it a good cleaning, and do a couple of modifications. The calibration tag lists it's next calibration as being due in mid 1968. Looks like it's overdue. :-)
The first mod is a meter protection mod that decreases the chances of frying the meter due to an "accident". It involves placing two silicon rectifiers across the meter in opposite directions. I use 1000 volt 1 amp ones for this. This mod is a good idea on the TV-7 series and the I-177 series testers also. Make sure that you test the rectifiers before you install them. Here's a picture:
The second mod involves the 40 or 50 year old or so electrolytic capacitor across the meter circuit. This one leaked bad enough to affect the calibration. This same cap is also used in the TV-7 series of testers and this mod works fine for them too. Been there, done that....
Finding new current production bathtub caps wouldn't be much fun so I used a Sprague Atom mounted on two gold plated 500 volt insulation standoffs. The original value was 100 mf at 15 volts. My replacement is rated 100 mf at 50 volts. The existing holes could have been used but I went ahead and drilled a central hole in the existing pattern. Here's a picture of what it looks like after installing the new cap:
Another mod was to use the solid state replacement for the number 83 rectifier worked out by Alan Douglas. It's simple enough to build using nothing more than an old 4 pin tube base, two 1 amp 1000 volt rectifiers and a pair of 10 ohm 1 watt resistors. I used the micanol base from a dead 809 and two watt resistors. "More is better". This will save about 15 watts of internally produced heat in the case of the tester and end the problems with the mercury vapor rectifier: This mod is reported to work fine on the TV-2, TV-7, and I-177 series of tube testers but I haven't tried it on those yet. Naturally, recalibrate the beast after you do it.
I plan to replace the paper blocking cap and all of the carbon composition resistors that have drifted up in value in the TV-10D/U. I have the parts and will be using WW and film type. I'll post pictures when I get around to doing the work.
At any rate, since the settings data for the TV-3 and TV-10 series testers appear to be identical, it makes sense to combine both designs of testers for this project.
I'm now in the information gathering stages for creating a settings data file for the TV-3 and TV-10 series tester as I have for other models of military testers. This file, as is all of the previous ones, will be available for free download. I'd also like to hear from anyone that is interested in proof reading the file as it progresses.

What I'm looking for right now:
I'm collecting TV-3 and TV-10 series contract data. I'd like to hear of who make your tester along with the information on the nomenclature tag. I'm trying to get an idea of just how many of the TV-3 and TV-10 series testers were built. Thanks.
Tech Manual for the TV-3/U and any changes for same.
Tech Manual for the TV-3A/U and any changes for same.
Tech Manual for the TV-10B/U and any changes for same.
Tech Manual for the TV-10C/U and any changes for same.
Roll Charts for the TV-3 and/or TV-10 series dated later than May 1st of 1966.
Any supplements or "changes" for the above manuals that I have access to.
Any other manuals or roll charts that will help the progress of this project.
I'm also looking for the little metal cover for the square storage compartment inside the lit. I think that this originally had "fuses"or "spares" printed on it. Mine is missing. ;-(
I'm also going to need a few more people to act as proof readers as the project progresses. Don't worry, I'm doing all of the typing, I just need people to compare what I've typed to the settings data that is on their cards or in their documentation and look for omissions or errors.
This project will be done with Office 2000's version of Excel in Excel Workbook format.
If you don't have Microsoft's Excel, or have an old version, you can download a free viewer for 32bit Windows OS's from: http://office.microsoft.com/downloads/2000/xlviewer.aspx
