I have pics of a 545B working!! I could not believe that it fired right up!! It is for sale if anyone is interested. I will E mail pics to anyone who asks Wally KC9INK

OK - I tried this. The Varta 3V batteries have welded on tabs normally for PCB mounting for memory battery backup. But if these are bent at right angles they solder right in. Now the new voltage of

My 577 displays the retrace problem. I changed C581 in the 177 supply and four resistors R552, R554, R556, and R558 (all 4.3K, which measured between 4.7K and 5K), but it did not make a difference.

Hi Steve, I have been out of town for the weekend for Holloween party at my son's just got home this evening. I do have the High Voltage Assembly how do you mean the trigger knob assy? I can get them

I seem to have found a board from the elusive 463 scope by comparing to tekwiki front panel photos. Does any other scope have a button marked "lock knobs"?

Hi. I'm a new member finding my way. I bought a lot of Tektronix scopes for the services when with Defence during Vietnam era and visited Tektonix at North Ryde (NSW) to see about repairs to (I think

For what it's worth, the power cycle counter, and on time counter are meant to be reset after every calibration. They are there to let the technician know how long it has really been since the last

Thanks Dennis, and everybody. I stand corrected, all these years I thought I had the 3 meter one. I never measured it, it just seemed long. I measured it today and yup, about 6 feet. Everyone with the

Gentleman, Thank very much to all of you for all the information provided. I managed to get the scope screen back to life by replacing the two 10.0K 0.1% resistors (R2012 and R2013) in the DAC

Thanks for looking. I don't think I'm going to be able to get this thing fixed though. I already spent money on new caps and bridge rectifiers and its still suffering the same issues. I'm very close

Hi Dennis, When you select Photos and type PG503 into the search all PG503 related Photo Albums pop up including mine. Or: /g/TekScopes/album?id=77086 Greetings, Egge Siert

Hi Jeff, This isn't what you were asking for exactly but I have a spare mustard color compensation box for the P6105 which I can send you if that will solve your problem. This would be for the 2 meter

Hi Egge Siert, Two questions: What is the link to the picture, and where did you find these? Dennis

Thanks Rolynn, The message archive here on Tekscopes should have many of his fine posts! He had a great sense of humor and a lot of knowledge about a lot of things to go with it! tom jobe...

yes the HF thing may be too narrow 16X30 in. unless you do as I did and add plywood top and angle it for easier viewing, my surface is 20X34 in. after top added. the item no. 60390/507 was $38.00 now

I found the cheapest HF cart (two shelves) to be flimsy, but the second cheapest (three shelves) can handle a lot of weight.? I have my 4x6 bandsaw on the inverted top shelf, and the other two

Nothing from the law enforcement end but there was some information in his obituary regarding his past electronics adventures. <https://www.since1928hull.com/obituaries/Jon-Batters/#!/Obituary> RP

Speaking of Harbor Freight, I bought some 275 pound (IIRC) rated casters there a few months ago for my workbench.? Maybe there's a way to replace the casters on a rack to beef up the weight
