I don't know what I've done to piss off the youtube algorithm for the last couple of years, but I'm glad it finally decided to suggest your videos...

Glad you found us and welcome.

What I love about that BNC conversion is that it is totally reversible. You might consider bagging the GR connector up and securing it inside the instrument, some future curator may thank you. I remember the first time I pulled the cover off of a 500 series scope...the manifest quality was just breathtaking. I think you are correct that this unit is good for another 50 years.

I love your work, your attention to detail & care is what this old Tek gear deserves. I've used leaded solder on these old Tek wafers but only alongside the proper solder. I think as long as there is some silver based solder in the joint, your ok. That said these wafers are not easy to solder and get a joint as good as the gals at Tek achieved back in the day. Getting zapped is an occupational hazard I think despite all the care we take. Thanks....DA.

The reason for the lead free was at the time it was all I could find with a high enough silver content 3%+. It makes the 3%

Very nice video. Please do keep them coming.

You probably figured this out already, but lead solder is ok as long as there is 2% to 4% silver. Silver bearing solder is usually a pretty good mix. Original mix was tin 60/lead 37/silver 3.

Thanks for the Info on the original solder formulation. I am not sure on it binging a timing issue but It was hard to find a suitably high silver content. Which is why I ended up with the lead free It had the highest silver content I could find, Sn 96.5 / Ag3.0 / Cu 0.5

@@ZenwizardStudios This is perfectly fine, and exactly the specs recommended by Tektronix in the 106 manual, section 4-2, 3% silver.
