Re: What removes sticker residue without hurting the blue paint?

 

FWIW, the contents of brand name solvents like Ronsonol are in their MSDS available via the web. The MSDS also usually list the CAS numbers of the constituents.
There are some tutorials on solvents on the web. They are classified in various ways such as polar (will mix with water) and non-polar (will not mix with water). These are helpful in finding out what they will dissolve.
I use naphtha on camera shutters, its a good degreaser. Ronsonol seems to be quite pure and does not leave a residue but is more expensive than naphtha from the paint store.
I had not known that Bestine thinner was hexane. That's useful to know because hexane is a good solvent for a number of things. I have not bought Bestine for some time but think the last I got was in an art supply store.
I think I will take your word for the cool flame part.

pure.

And NO! I do not want to EVER see that terrible force be used again. We should never forget how terrible war is, not just these bombs, which took the lives of a very small percentage of the 50 Million Plus lives that were lost in WWII.

Eric,

Actually, Hiroshima and Nagasaki were neither of those. Several other fire bombings in Japan killed more civilians. The most deadly such raid took place in Tokyo on March 9th, 1945. This one raid killed at least 100,000 civilians and left over 1,000,000 more homeless. The Tokyo raid was pivotal in the decision to use the atomic bomb, since such a loss of civilian life appeared to do nothing to bring the Japanese leaders to the point of surrender. We bombed all of the major industrial locations in Japan, in fact, these two cities were some of the very few that had suffered little or no damage in previous attacks, still the Japanese leaders refused to surrender. What the atomic bomb did was to bring even the most ardent Japanese war hawks to the realization and acceptance that they faced total annihilation and extinction as a nation. Truman played the bluff card and told the Japanese that we would continue to reign these bombs on the Empire if they did not surrender. The fear that the next bomb would be dropped on Tokyo was the key. The truth was, we had no more atomic bombs that could have immediately been used. What is not taught or barely glossed over in the revisionist history books is that these two bombs, as terrible as they were, saved Millions of Japanese and American lives that would have been lost in the invasion of the Japanese Home islands. One only needs to look at the invasion of Okinawa as a preview of what such an invasion would have cost in blood and treasure. What is more disgusting and despicable is the total disregard of the Japanese leaders to the terrible suffering and loss of life among their own people. Like the NAZI's in Europe, the Japanese leadership was more worried about saving face and having to admit that the Allies, led by the USA in the Pacific had soundly beaten the supposedly "Superior" Japanese warrior. The Japanese continuously underestimated the US resolve, our fighting spirit and most of all, our industrial capacity.

Re: Looking to buy or trade a simple XY monitor

 

Don't have the old school probe Supply they are damn rare. Even when you
were plastic one is hard to find. Even when I was at tektronix I needed one
ended up building it out of parts from the stockroom.

Re: NEW to the group

 

Eric, I am not optimistic about our chances of not using nukes again. There are groups in the world who would not hesitate to use a nuke if they got their hands on one. I believe the USA would use nukes in retaliation for an attack on America without really knowing who set off the nuke that attacked America. Even an angry president could go ahead and start something like this. Our world without nuclear war is on a tenuous footing

I prefer to try not to think about this. Much more fun using my Tek Scopes to repair old stereos and transceivers. I am old and fix these things just for fun. I charge what it costs for parts and other supplies. I don't charge for labour. I have more work than I can handle. I was amazed how many people are still using stereos and hf transceivers from the 60s 70s and 80s. Some of them have been kept in absolute pristine condition on the outside. I have 2 465s and 2 22something scopes. I actually only use two scopes at a time on my bench. I just like having spares. The 465s are my favourites to use, the 2200 series is may favourite to repair. Taking apart a 465 is not easy. I repaired one for a friend and a simple capacitor change on a power supply line was somewhat difficult. I love it when the using the motto, (always check the power supply first) actually works. It is a method of repair that is used by me religiously. I don't of course just check voltage, I also check ripple. I have a new digital scope (not Tek) that will immediately give me the voltage and amplitude and frequency of the ripple with one button push. Still love my 465s best. I hope it never takes offence at my little indiscretions with that new (younger and sexier) Hantek babe. It was never for love, just physical.


Re: Tek 7a13 mechanical to LED display conversion ? / 7ct1n user notes ?

a) Is there a way to convert the 7a13 mechanical ( "veeder root" type ) display to the LED display ?
Did Tektronix provide any field Tech notes for doing such ?
Does someone have the schematic & parts list for the LED module ?
( does anyone have that module from a dead 7a13)
Could it be transplanted into a 7a13 that has the older mechanical module ?
Tektronix never did this but I think someone on the list may have done
it so a search through the archives may reveal something. I know we
discussed various options for the ADC and display because I was part
of that.

The biggest problem is finding a small enough LED display. One of
those tiny OLED graphic displays could work but would be more complex
to drive.

b) I am trying to understand how to use the 7ct1n Curve Tracer in a 7704 with the 7a13.

Does anyone have a set of simple notes written up for this ?
The 7ct1n manual seems a tad confusing ...
The 7CT1N works with the 7A13 like it does with any vertical amplifier
set to 100mV/div.


Re: NEW to the group

 

I should hope that no one ever forgets about Hiroshima. Or Nagasaki. It would seem difficult not to know about the places hit with the most deadly and indiscriminatory bombs in the history of the world. Although they seemed necessary at the time, hopefully they will never be used again.

About (Hiroshima)-- I would not say everyone at least in the USA; most do not know who are presidents past of the USA !!

Hi, my name is Joel and I have been reading the group messages for some time now and enjoy them. I was a sonar technician (Submarines)in the US Navy sometime ago, very early (1970's). Now retired I am drawn back to playing with the "TRONS". It is easy to see there is a abundance of knowledge here. I look forward to being guided by the group on some projects.

Re: What removes sticker residue without hurting the blue paint?

 

Goop works well on all surfaces i've used it on.

Not necessarily at the same time. A hot air gun works well for
initially trying to peel the label up and also works with new tape to

And I don't now that naphtha is any worse than acetone or lacquer
thinner or alcohol as far as danger due to flammability. Back when
rebuilding carburetors was a thing, I always had a laugh at the
warning on the carburetor rebuild kits about not using gasoline as a
cleaner and solvent because of flammability when acetone and such were
even more so.
