Re: TEk 475 removing replacing big electrolythics
Hi Alan, Now I am sure others on this site may chastise me for my methods, but here is how I remove these big cans from the 7000 series boards. There was enough stand-off between the cap base and the

TEk 475 removing replacing big electrolythics
Hi Everyone, I need some guidance. I have removed two large caps which were damaged, but in the process of removing them I may have caused more damage, I can't find any clear pcb layout masks in any

Re: working 661
http://w140.com/amperite_delay_relay_datasheet.pdf According to page 3 of the datasheet, the 26NO45 would be a 26 volt heater, normally open contacts, and 45 second delay. The absence of a "T" at the

Re: working 661
The 519 manual calls out the same Tek part number but also describes it as a 26NO45T in the parts list. The schematic omits the "T" in the part number. Hope that helps! Dave Casey

Re: Testing Electrolythics and ordering replacements
I sprung for one of these on the strength of your report. I'd been watching many auctions of similar things, but most ship from China. It's inexpensive (below my what-the-heck threshhold) and can ship

Sorry, meant the Amperite part#, looking to source a replacement. Similar part died on my 545a some 20+ years ago. I ended up (non destructively) sticking a damn button of the side of the unit to

Re: working 661
I'm not honking, but the Tek part number for that relay is 148-006 (so probably 148-0006-00). Dave Casey

Honk! triggers from 'cal' on 'A' channel only, but it's a start. Needs a new thermal delay relay too - got a part # on that btw?

Honk if you have a working 661. (Kurt honks)

Re: Tek 564 issues
Interesting. Now that you got me thinking about it, I noticed one other important difference: The original CRT has a round CRT in the logo, and the replacement has a square CRT in the logo (confirming

Re: Tek 564 issues
Hi Paul, You mention the difference in CRT slide pads (6 versus 5) while the part numbers are the same 154-0410-00. I don't remember the layout of my 564 CRTs and it's not visible when the CRT is

Re: Testing Electrolythics and ordering replacements
Alan, This looks like it would be very handy to have. When you have a chance to use it we will all be interested in how well it works, and what, if any, drawbacks it has. Thanks, Dennis Tillman W7PF

Re: Windows (OT)
Newer systems use a recovery partition instead of a CD or DVD. But you can make a bootable USB flash drive from the recovery partition, and you should do that in case your hard drive fails. Windows

Bob, I think that I may have a Dell recovery disk. If I do I can make a copy and send it to you. It will only work on a genuine Dell computer. There is a hidden partition on the hard drive with the OS
