Never could find a product specification PDF... "Halogen free flux" is about all. I can say I have used it on assorted Tektronix ceramic strips, successfully. (Re a 575 mostly, few other odds and

Nice to know it exists. I wouldn't have thought to look for audiophile solder! I wonder what else is in it? <david.w.holland@...> wrote:

The problem is that tin-lead-silver alloys with 3% or more silver is unobtanium now; nobody makes them any more, likely because of limited demand caused by the cost of silver. If you want it you'll

I am using a similar mix but with 3% Ag, because the Tek service manuals specify a minimum of 3% Ag for use on the ceramic terminal strips. -- Dale H. Cook, GR/HP/Tek Collector, Roanoke/Lynchburg,

Barry, Clean J/P3032 ends. The coax wire and socket can be dirty even though they look clean. The switch for CH2 that is connected to the collector of Q3031 labeled 7 could be dirty. Mark

Barry, Correct. High voltage multiplier. Mark

My 547 still has it's original roll. Other than requiring two (such an unreliable machine!) tube replacements, it has never required a component replacement.

Yes without transistors is fine. Craig

Channel 2 will trigger on Channel 1 and External, but it does not trigger on channel 2. This is what I am working on next!

It started working. Not sure, probably an intermittent problem.

I assume high voltage multiplier.

Craig, I had already removed all of the transistors from the boards. Do you want the boards without the transistors? I can provide the pots. Barry

If you would prefer the ease of use of tin/lead/silver solder, you should look for Sn62Pb36Ag2 solder. Kester, AIM Solder, and ChipQuik all make it. Digikey has Kester and ChipQuik in stock. Mouser

If anyone needs a part let me know. Barry I could use the pots that deal with triggering and horizontal control their plastic knobs, A7 and A8 trigger boards. If you want contact me at.

Hi John : What a good answer to my question, I hope you don’t mind my response to your personal mail. I did not mention that I have JFETs instead of a matching pair of 12au6s in both

Barry, One is what I need. I am in the states on the east coast. Thanks. I am considering the multiplier also as a spare for my plain and B version. Mark

The one that I have is in excellent condition. Are you in the united states? Can you use just one? Barry

Hi Mark, I used one of them. I cut the clear plastic time mark rings off and replaced it with one that had a broken knob. Great fix! I seem to be better at the hardware restoration than the circuit

So did the first Tek portable solid state 'scopes beginning in 1966, which also used the ceramic strips. When I bought my Tek 453 about 1994 the roll was missing, but I already owned a spool of
