SRPP 45 Amplifier repaired

SRPP 45 Amplifier repairedOld triode tube single low frequency amplifier became out of order and repaired with my minimum effort before long. As a symptom, the speaker out put on both side decreased gradually and finally disappeared even at maximum volume control.

I had some suspicion on supplying high voltage on the plate of power tubes from the beginning and I was right. Immediately after opening lower cover I could recognized the criminal, it was the initial capacitor 47μF/350V with the the trace of liquid leak, the former capacitor for rectifier smoothing circuit for the rectifier tube.

20 years used capacitor was replaced into new one and its original performance was re-acquired safe. All the electric device and equipment around myself should be checked on capacitors at least once a few years. Though semiconductor lasts unlimitedly but electrolytic capacitor has limitation because of loss of electrolyte.

20 years is too long, remembering the past, rectifier and one of UX45 tube were lost because of inrush current, this 47μF/350V might have been the reason for the accidents. As for the rectifier in my personal computers, over 10 years, how come? Any time will do to be out of order!

Things change continuously

Things change continuouslyThe Prime Minister of Japan would be elected today and Kishida Cabinet is inaugurated, but in a month general election will held, so it's too short to perform anything, just a pretence and gester at all. Noisy days with loudspeakers will begin soon. Let's give it up as a natural phenomena.

I'm at a loss how and where to go as my hobby has come to some one break, English guide training course would be extended more half a year and one of photo school will stopped but another one would be continued till the end of this year.

The possibility of my returning to former business cannot be denied next year because one of a stuff is going to resign sooner or later. And how long my situation would continue in future is unknown. Things change involving everything regardless one's preferability.

Hope for epilogue

Hope for epilogueLight Up color has changed from red to yellow on the Tower of the Sun at Suita and on Tsutenkaku at Tennouji, the inhibits of State of Emergency and the abolition of measures such as prevention of spread are the reason. Though we hope COVID-19 would disappear to end, there is no reliable reason to come out again.

The side action of Vaccination is reported as an unfavorable reactions because enough preliminary experimental research and development had not been done. Ordinary vaccinated people were the human experimental targets at all. Probably, another problem would surface one after another in future.

Once SARS CoV-2 diminishes gradually, next pandemic will appear one hundred year later, remembering the past Spanish Flu came the same period ago. Try and error will continue for a while.

How long Photo Industry keeps the same?

How long Photo Industry keeps the same?2 hours drive early in this morning took him from Osaka to Northern Shikoku Takamatsu, so shown on the Google Map. As I mentioned before, it's the first day of the released from mental and substantial restraint by the disaster of SARS CoV-2. So, all the people will come out from the clogged circumstance this fine day as a matter of fact.

Consequently, it is inevitable that all the resort would be crowded with families, I wonder if he could come back without suffered from traffic jam? So, as is my manner not to go out in terrible congestion.

Though my Smartphone is 7 plus, it works as a camera far better than my exaggerated photo shooting equipment, this cannot be confessed at all, firmly closed secret. The fact that 4 of my photo works in 5 were done by Smart phone proves it!

Then it guides me to the conclusion, I cannot find any good reason to go out for photo shooting accompanying with heavy and troublesome equipment at all so far as a smart phone is in my pocket?

A rumor is chattering that all the representative camera manufacturers will disappear sooner or later because of mainly prevailing of the hi-performance camera equipped in Smartphone though it is a matter for regret. But, I stay in the field with my desperate efforts.

Temporally extended hood set on the original hood takes effect to prevent inconvenient ghost and frare when back lighting condition.
This is said especially on old designed lens such as RMC Tokina 400mm/5.6. The hood should be as long as possible and as close as narrower opened angled.

Of course the inner surface of the hood should be specially modified to consume any oblique reflecting light source applying anti- flocking cloth. This principle, shutting out any unnecessary noise like light source does not be changed if imaging surfaces might be changed from silver-salt film to digital imaging sensor.

The Universe will be a battlefield?

The Universe will be a battlefield?My son failed to shoot #5 Epsilon last morning at Kimotsuki Kagoshima Prefecture in spite of long journey from Osaka.

Later information told the decision to stop launching was done only 19 seconds prior because of some inconvenience not in the Rocket itself but in the software of RADAR equipment on the ground. Remember the past, he also failed that at Tanegashima last time.

If we force it even though there is a problem, it will lead to a lot of labor and money loss, so it would be a reasonable decision to cancel. There must have been engineers who were more disappointed than him.
It is our earnest wish to work hard on "Rocket Technology" at all.

Once we fought in the War for supremacy on land, sea and air, The Outer Space is the next Target as the former PRC leader Deng Xiaoping said, "Those who have the right to control Universe control the world!".
