If you have some bad strips, I have quite a lot of new ones and ones I have
salvaged with a solder sucker. You can find them in my Parts Shop.

Subject: [TekScopes] Re: Back to soldering ceramic terminal strips
Hi David,
As I'm still learning good technique for reworking ceramic terminal strips
I'm hyper-concerned about wrecking the scopes I work on. The one I'm
restoring now has been worked over quite a bit by a trouble-shooter who
lifted wires and components here, there, and everywhere chasing down
problems. My inclination is to, like with convetional terminals, wick out
the nasty old solder and make a new, shiny soldering job, the idea being to
restore the orignal beautiful work done by Tek. I'm finding that approach to
be ephemeral at best. So now I wick off only excess solder and then reflow
with a bit of the silver bearing stuff. I get mixed results, still too much
leaching of the silver plating in the strip notches. Someone said it's nigh
impossible to avoid that so I guess the terminals, bright an idea it was by
Tek, is really a one shot proposition.
Stan has Tek solder spools for sale on his website so now my solder hunt is
done.

I have a spool of the Radio Shack 62/36/2 that I bought years ago and
while it is thin, there is certainly enough to do a reasonable number
of connections if you do not overdo it. The thin size is because it
is intended for surface mount parts that use silver metalization.
The only real electronics store here in the St. Louis area
() has an old bin full of the Kester
62/36/2 solder tubes but their inventory management is not good enough
for them to be listed online. For the price, I think it was about the
same value as the Radio Shack silver solder. They are certainly less
expensive online even with shipping.
This seems reasonable although it is no clean flux instead of
activated rosin:

&hash=item5880d27c4b
That 4% low temperature silver solder (not the lead free stuff) from
Parts Express would no doubt be better but sure is expensive. Better
to use the 2%, extra flux if necessary, and use a good lower
temperature soldering iron.

Well, gentlemen, you made me do it. I rose to the challenge and dropped
by the local RS. No 62/36/2 on its hook. The computer said they had
two in stock. Shoplifted, no doubt. But while looking over the
shoulder of the store clerk (yes, that's what they used to be called) I
asked what the specs were. 0.015 dia., came the reply. Worthless! Too
small for soldering ceramic terminal strip notches. You'd put half a
spool into one notch if you cleaned it out and refilled it. $3.00 a tie
point is a bit too much. Not much better, the stuff I got from MCM,
Kester made 0.020 dia. for about half what RS sells theirs for but no
bargain because I had to pay shippijng. So the hunt goes on for 0.031
or thereabouts, ....TekScopers shall not be forgot!
Confirmed. While Xmas shopping yesterday at the Sherman Oaks Mall in
LA I stopped in at the Radio shack and found two Radio Shack part #
65-035 for $6 each. I bought them both....
