:rockon:I admit I love my G-22000 but my AU-9500 is a lot more fun. I would say my G-22000 is made to enjoy with the look and the AU-9500 is to enjoy with your eyes closed! If you understand me!:rockon:

If you find out the problem with the protection circuit, please let me know!:dunno:

Funny, my G-22000 usually gives this problem when the weather is wetter and colder, who knows!

Would it be a Sansui AU-20000, a TU-9900 and an SR-737 that appear in the 1976 star is born movie?

Altec Valencia, right ?

Sansui G-22000!:rockon:

One question: where to connect the multimeter leads? Should I connect the positive and negative on the same fuse holder? Even knowing that the fuse F002 F004 are positive?

:lurk:

I have my E-70 connected to my Sansui AU-9500 and play better than with the G-22000. I really love this integrated, if I had the E-90 they would surely be connected to the AU-9500!:rockon:

So ... sansui is going back to the bench! He's turning on too fast! And this is causing a click on the speakers, in fact it's the noise of the relay setting!

I understand! So 15mV would be something around 32mA. And to get to 35mA I would have to raise the bias to about 16.5. Should I change from 15mv to 16.5mv?

The last question: -What would be the best fit sonically speaking 30mA or 40mA?

This I understood, I would like to delve a little more!

I set it at 15mv as you instructed, I just wanted to know how you got this result!

Could someone explain me better the mathematics of bias tuning measured through the 0.47kohm resistor? I did some accounts and got the following result: 30mA = 14.1mV; 40mA = 18.8 Are my calculations correct or am I missing out on the way?

Thank's Kev!

It's normal?

The only difference I noticed was that the amplifier is turning on faster, the delay of the protection circuit takes about 2 to 3 seconds, before it took about 5 to 6 seconds to set up the relay. I do not know if it could have been due to replacement of the grinding bridges or another component...

I received yesterday from the technician my Sansui AU-9500 with all the noisy transistors exchanged as well as the rectifying bridges and 2 jfets. I had asked him about the offset settings and bias, and he had told me that everything was okay, according to specs. I turned the amplifier on and at...

What a coincidence, my AU-9500 also returns tomorrow !!! changed 20 transistors, 2 jfets and the two rectifying bridges!

The second image is about import taxes!

Unbelievable!!!!

I truly consider myself a hero by being able to live comfortably as much as possible and have some vintage and rare items in this country. Through such an economy it is almost a miracle I can enjoy a Sansui G-22000, a pair of JBL4430, a pair of Wharfedale E-70 a TU-7500 tuner and if God help me...

I'm sad because the mouser's transistors arrived! I paid an absurd tax, the order cost me nearly 100 dollars, and the order amount was 4.98 US dollars, a total and absolute nonsense, it was not my passion for music, audio and Sansui brand would certainly have refused delivery. But what I can do...

The problem is that every order I make on the mouser takes 11 weeks, if the order is not retained in the customs. So I think I will not make a new request on the mouser, but ask for the technician to find a replacement here in Brazil itself, they are only 2 jfets, the other transistors will all...
