Hi All, Thought folks might be entertained by this picture I found. Currently helping my wife with downsizing her mothers household. Came across this book:

Dom, The filament windings can be left on or taken off. Check the high voltage when they are replaced. Clean the high voltage area to remove dust, dirt, etc. to eliminate leakage paths, if you have

Eric, if I understand correctly, the board you are making for the 7854 isn't a replacement for the 067-0587-xx boards, but something to do with the digital capabilities of the 7854, is that correct ?

Andy, if you need lots of pictures of the cal fixtures let me know I have a -01 and -02 here in the lab. I am also in process for a test board for a 7854. I had a unit arrive today.... destroyed by

Glad it was something so simple and cheap to fix -- just a 555 instead of some left-handed unobtainium hydroxide. -- Cheers, Tom -- Prof. Thomas H. Lee Allen Ctr., Rm. 205 350 Jane Stanford Way

HI Mark, Thanks for your advice. I can see the one's you're talking about on fleabay- they're certainly a good price. I'll be replacing all five because I'd imagine the corrosion that ate through the

Hi Mike, That's terrific- certainly a lot cheaper than the diodes from Digikey. I hadn't seen that site before and it looks like they have some great stuff! I'll have a browse now and I'll let you

Quick update to close the loop. I went through the components related to the NE555 timer and concluded that it was, indeed, a dead IC. I injected a 20.48 kHz signal at the output of the NE555 and the

I have a 7904A, that I intend to keep in good working order. However, I've not seen many cal fixtures on the market and reckon the prices are only going to go in one direction for the near future. I

Greetings, Just FYI, both of my Ibico punches are combination machines. One has an electric driven punch the other is manual. Both have a section on the top of the unit used to install or remove the

Get the comb binding punch and the installer as well. Two pieces are necessary. -- Michael Lynch Dardanelle, AR

Get a Comb binding tool if you can get one cheap. -- Michael Lynch Dardanelle, AR

re: multiple copies, yeah Dave, it can get pretty bad pretty quick! My wife has an easy solution. I can have as many manuals as I can fit in one double drawer file cabinet. :-) For my part, sometimes

Why would one want multiple paper copies of a manual? I copy pages (mostly schematics) when I want to annotate them while troubleshooting, but I have eight file cabinet drawers of manuals. Having

Remove the comb and put it in a 3 ring binder? I've seen manuals from other manufacturers where they show a picture of what the manual will look like but when you get it it's actually in a 3 ring

Also, a number of my Tek manuals, including the one that I just printed out from a PDF, were punched for both comb binding and three ring binding. Most of the manuals that I have with three-ring holes

I have no argument with what you're trying. Go for it!

Hi Folks, Has anyone compiled a list of the electrolytic caps for the TDS540? I’d rather not pull mine apart until I have the parts in hand. Thanks, Stefan

Hi Paul, I didn’t bid, but I sure did consider going over to Tuscaloosa to get those three 575 at $10 each. :-) FWIW, I see yet another 576 up there now - this one is in Vegas. Ends tomorrow

I have worked on several SG503;s and a common problem causing dropouts is failed solder joints on the range switch to he board that is right-angle to the main board. But re-doing these requires
