Hello, maybe this video helps you - soldering SMD leds, down to 0603 is doable. Just be careful not to "crush" the LED with the pincer when it is

Jamie, Same here! I was trying to figure out a way to pick this up or make arrangements. I just cannot make it happen. This is a treasure trove of great stuff! -- Michael Lynch Dardanelle, AR

You have to read the doc of the 7S11 and the sampling plugins as well. Note that the 7S14 is a complete horizontal and vertical sampling unit and the 7S11 is just a vertical plugin for the 7000

It makes me so sad I but I simply can't afford to travel and buy this beautiful gem right now. I thought someone here might be interested: https://www.facebook.com/marketplace/item/472746093502260/

Dan, You are correct. The 535 came from Stan Griffiths at the Vintage Tek museum in trade for a 570 they had. He said he tried to explain that Tektronix was a post war company and that any Tek scope

is the 453a-1 transfo the same,ie the one in the hv compartment?,as mine is stuffed!,cheers Paul m3-vuv.

Take a look at http://w140.com/tekwiki/wiki/7S14/Repairs and the 7S14 circuit diagram.

Congratulations! It will be the first of many. -Chuck Harris michele.trozzi@... wrote:

The cell voltage was 2.74 V, now it is 3.23 V. I just successfully replaced. I followed your advice, using a second cell soldered to pins 4-8 of DS1210. My wife saw me during the work and told me:

What is the cell's voltage now? -Chuck Harris michele.trozzi@... wrote:

Hi All, A long time ago someone said it is possible to lubricate the Oilite Bearing if you place the motor in a vertical position and allow oil to seep into the shaft area. I have not been into a

Reading the manual I have understood that after data loss in the NVRAM, you can do a simple re-calibration using the internal calibrator. This can allow to make just qualitative measures. All

I suggest that the HV Multiplier is bad. I had a 468 and a 475 that both had bad HV Multipliers (Both shorted). On my units with a shorted HV Multiplier. there was no trace until the service jumper

Lots of good ideas but I cant get back to this problem for 10 days or so..So your suggestions have to wait I guess...steve

Hi Jr: Same procedure as the 485.  Tap on every variable component including pots, varcaps, switches and connectors. The 465B uses a voltage doubler so you can check it the same way.  Just make sure

Reed, Thanks for the Tapping Trick on Potentiometers! Any Tips on a 465B with Short Traces? JR

JR, I tried just adjusting x1 gain pot, assuming that it may have drifted over time ( I received the scope in that condition ). When I turned the pot, nothing happened to trace length. I measured the

Hi Gang: Whenever I have a 485, or any other scope for that matter, in my shop for refurbishing I always tap on every potentiometer with a screwdriver handle end while watching the CRT.  If I see any

Hi, why 7S14 need cells to bias bridge diodes, and 7S11 no? I possible to feed bias in 7S14 with +-50v and resistors, just like the 7S11? Thanks Regards

Took the keypad apart and the LED was burnt out. Got some replacements on order. I’ll have to do some practice to see how to solder on the replacement. Manuel
