JI1FGX/DU9 Oscilloscope blew smoke.(2011/02/20)
I had a cold and was in bed for about a week.

Starting with a sore throat, followed by fever, chills, runny nose, cough, and a parade of cold symptoms.

It was hot, but I was sleeping under the covers, sweating.
The fever still did not go down, so I took him to the hospital on the 16th to have him tested to make sure it was not dengue fever. He was taken to the hospital on the 16th to have tests done to confirm that he did not have dengue fever, and was prescribed cold medicine.

Lily was historically (about 400 years ago) as a Cavalier.
."It also warmed the owner's knees and feet, sometimes acting as a substitute for a hot water bottle!"
He spent the night sleeping with me, so much so that there is a description that says, "I was so sweaty. It made me sweat a lot.
My cold is much better and today I'm CQCQCQ on 21MHz after a long time!

And I prepared an oscilloscope to check the non-working TSU-6.
TSU-6 (Tone Squelch Unit) for TM-701 purchased at auction did not work from the beginning!
This is also a Tektronix 2445A that I bought on Yahoo Auctions a long time ago and had sent to me from Japan
150 MHz digital oscilloscope.

However! After a few moments of turning on the power, white smoke is billowing from behind: ！！！！
No longer able to repair the tone squelch unit, the oscilloscope was disassembled.
What was done was film capacitors and resistors
I immediately searched the Internet for Tektronix2445A 0.068 and found it!
."tektronix 2445Aup in smoke - Topix"
Looks like some of you are having the same experience.
In one of those exchanges.


I downloaded the Tektronix2445A service manual as soon as I saw that

What had been hit were the capacitors and resistors in the power supply circuit.

Here is where you can download the manuals, operating and service manuals.
http://www.bitsavers.org/

Click on PDF Document Archive then tektronix then scope then choose the manuals you want to download.
Determined that the absence of the parts will not affect the overall operation for the time being.
While Lotlot instructed me to remove and reassemble the parts, I went on the Internet toKyoritsu EleshopOrder parts to
We don't communicate well with each other in words, but what we do is quick and fast because we share a common goal!

I just talked with JA5BXB, who I communicated with today on 21MHz, about the difficulties we both had in arranging parts in the region,
In this way, Mindanao may not be much different from a local city in Japan.
I took a long detour, but after checking the operation of TSU-6, I confirmed that MN6520 is still not working.
Repair of TSU-6 is also completed by replacing it with MN6520 (500 yen per piece), which was also purchased from Tanqing through an Internet auction.

This was the first time that I had ever been offered an immovable item at an auction that was not marked "JUNK," but it was a good experience.
Amount of loss= 1900 yen for the winning bid + 500 yen for domestic shipping + handling fee + 900 yen for EMS
What you get (priceless)＝Explain to Lotlot how to find information on the Internet + how to read a circuit diagram + how to use an oscilloscope
