What a tremendous loss, but that's just to say what a tremendous person Chris was and what he meant, and will continue to mean, to us.- SJ
Read from bottom up. Chris was so through with helpful hints. This is sad indeed.Tubemonger

Dear Ted and friends,
Thank you so very much for your kind words. It has been a tremendous comfort hearing from all of Chris' "tester" friends.
I'll send your tester out as soon as possible (I'll email when I do so).
Thank you again.
Cheryl

Hi Cheryl:
It was both shocking, and very sad to hear about this unfortunate news on the Audio Asylum. We had just exchanged e-mails with Chris on last Monday, and as usual, Chris gave us great and thorough advice. All of us in the tube community drew comfort in knowing that Chris would be there to answer all our questions about Tube Testers, and do a great job fixing these. He was one of a kind and would really be missed.
You must be tied up with more important things. Please, there is no hurry to find or send our tester back (we do have a backup testers). We'd rather you cash the check now, and wait till you are free to take care of less important matters like these.
Please do not hesitate to contact us if we can help in any way, now or later. Our thoughts and prayers are with you at this difficult time.
Kind Regards,
Ted and all of us at;

I'm very sorry to inform you that my husband, Chris died last week. I received your check yesterday, but will not cash it until I locate your tester. A dear radio friend of Chris' (Mark Oppat) will be helping me go through his workshop in the next few weeks. I can assure you that Chris kept meticulous records and his shop was always kept in near spotless
condition. Unfortunately, Chris would know exactly where your tester is, while I will need help in finding it.
As soon as possible, I will ship the tester to you. I appreciate your patience and understanding.

I don't have anything written up about the 580 tester. I did just review the manual and found a couple of items that could use clarification.
(a) The selectors should all be set to the chart positions before the tube is placed in the tester.
(b) Allow the tube to warm up for about one minute and then press the line set button and set to the line mark.
(c) The bias is most accurately set using the meter on the tester. There are two ranges (5 and 50 volts) and make sure you are on the proper range for the bias required. The bias dial will give a rough idea of the voltage. Press the bias button to get the meter to read the actual bias going to the tube and adjust the dial if necessary. Some tubes like the 6922 are tested using a bias resistor connect through the jack under the meter. I made you the adapter to test such tubes.
(d) Now check the tube for leakage by rotating the knob through the positions. The manual covers this--but you will have to decide what level of leakage is acceptable. In general--a tube with leakage of 250K or less is considered shorted and should be discarded--but the meter goes up to 50 megs. Remember that the shorts test needs to be made for all sections of a tube. At any rate--tubes with a leakage of 250K or less should be discarded and no further testing done. You can easily damage the tester by testing a shorted tube for mutual conductance.
(e) I know that it says to use the locking S4 to do the mutual conductance test--but I don't suggest this. If a mistake is made and the 81 fuse bulb lights up you can quickly release the switch. If the switch is locked down something might burn up. So--I suggest using the non-locking S5 to do the mutual conductance test. Hold the button down long enough to get a stable reading--perhaps 10 seconds or so.
(f) The locking S4 button must be using when doing the gas test. S4 must be locked down at the same time that S8 is locked down. Then the meter is adjusted to zero with the Gas Zero adjust knob on the operating panel. The gas/grid current may be read by pressing S9. A good tube will show little upscale movement. Some typical rejection points for gas are in the manual--but here again you will have to set your standards for allowable grid current.
Note: There is a mistake in the gas test instructions. It says to depress the Gm lock button and then reset the line. This is wrong--the line is never set with Gm buttons down--for either the gas test or the mutual conductance test.
(g) I also noted that the setting for the 5AR4 shows a dial setting of "14"--you should use "10" to provide a proper reading. On the 580 they combined the rectifier meter shunt adjustment with the voltage regulator test pot. It works only fairly well. Testers like the 539C don't try to make the VR pot do double duty.
I hope this helps. I really do not think this tester is a good one for a beginner to start out on. I would master it's operation with experienced people and then teach your student. Many areas or tube testing require judgement and experience.
The 9-pin socket saver should be held down with one hand while the tube is inserted or removed. To test tubes with a 10 pin base remove the socket saver.

I've known Chris for a few years and I feel true sadness knowing he will no longer touch our lives. I am happy for him as I know that he is now in a place of certain bliss. We will all be meeting him again one day...........--Bob
I, too, only knew him through emails. I had two testers recalibrated by him and he was unbelievably helpful and a joy to deal with. He will be missed.
Chris took alot of time with me in helping get my tube tester. When I finally got my mint 747B he worked on it and got it back to me in record time so that my brother could deliver it to me in person. He even volunteered to ship it out before he received payment to make sure I got it in time.Just an extremely knowledgable, helpful and trusting individual - the world can never get enough of that sort and although I didn't know him more than through our internet contact I feel like I've lost a friend.........
God Bless Chris!
A link to this loss to the audio community will be forever posted at the Asylum. Not having gone through this, I can't imagine how the family feels though I have an inkling. We also lost a dear friend and my wife's business partner yesterday. So Chris, met Mary , she's a doll that lived 83 years to the fullest.
I bought a tube tester from him the beginning of December and while I really only knew him through our emails, it is easy to tell when someone is just a nice person. That was Chris. He even sent me extra fuses for the tester since they were "hard to get".My heartfelt thoughts and condolences go out to Chris's family.
Sincerely,
Dan
Bought my totally refurbed tester from him last year. He did awesome work. Great lost to the DIY tube world. My thoughts go out to his family.
I'm very sorry to hear. Chris was a joy to know...
Chris' knowledge and skill with tube testers was very rare. The world is going to miss him.Just an fyi from one old person to perhaps some other oldsters (and maybe some not so oldsters), while we can't change our genes, we can get 30 minutes of cardio excercise three times a week, minimize the food we eat with fat, saturated fat, and cholesterol, and get our cholesterol (way) down. Chris would want the tube lovers to carry on our enthusiasm for tubes and the rest of life.
Cheryl, may you and yours get through this with gods help and wisdom My prayers, as I am sure the rest of the inmates, are with you and yours..Chris was a great man, one of the few that you could trust in business and in life.I was wondering why your e-mail address was the reply to address last and this week. I surely never thought this was why, I am truly sorry for your loss, He will be missed by many people was respected by many and I for sure will be one in both of those catagories.
God Bless and if there is anything at all I can do, please do not hesitate to e_mail me. Antony Charles - Bearlius_Max
Sorry to hear this. He will be missed dearly. He rebuilt my Heathkit TT-1A over the teseter on the antiqe radio tester forum. A wealth of information and patient as ever.My condolences to all who knew him.
Chris rebuilt my Weston 985 and really helped me understand its operation and idiosyncracies. A totally humble guy and an obvious wealth of information and understanding on tube testers. It certainly leaves a void that will not be filled, certainly on this board. How many people out there know what he knew? Maybe nobody.It sure reminds me how dependent we are on a very small crowd of dedicated audio craftsmen. He'll be missed, for sure.
Stephen
He restored my TT-1A and became a constant source of tube advice for me. I will truly miss him.Pacha
The recent email exchanges I had with him, he indicated had been having some health problems but mainly with his back. He will be missed by all of us. Our condolences to his family.
God Bless him and may he rest well.. Chris did a world class job rebuiding my Hickok 539B tube tester 2 months ago. I hope his family finds peace and knows that he is now in a much better place with all of his loved ones. He will be missed by many people. Just think of all the world class technicians that he is now banging ideas around with right now. Rest well Chris Haedt! John C.

"The truth is out there"
Very sad, but probably not terribly surprising. Chris, I believe, experienced prior heart attacks. The first came at a very young age. Probably heriditary. He often spoke about how much time he had left. His recent back problems somewhat overshadowed the cardio issues.I am shocked and very saddened. Chris was a good man.
Sorry to learn that.Certainly one whom I would like to meet up there when my own time comes. A real nice guy.
I only knew Chris through email exchanges, but that was enough to build a small bridge between us, and I am most saddened by this news.
Regards,
Geoff
Chris was a good friend of mine......I am so shocked and deeply sadened to hear this news. We have lost a truly great man in this hobby of ours.......Balekan
He was a great person, knowlegable and willing to share, even with newbies like me! My condolences to his family, Tony

This is very sad news. I recently bought a tube tester from Chris, and had the opportunity to talk with him by phone and exhange several emails. He was very knowledgeable, but also a gentleman and one of the real good guys in this business.
God bless him.
about our 580 he just finished working on. He was a real fine Gentleman and very helpful.
TM,Condolences to his family. I know he's in a much better place. Walking and talking shop with all the greats...
