С ним, вроде как, тарелочки чище играют. Других изменений по сравнению с TL 084 CN (у меня в комплекте такой оказался) не обнаружил.

Чтоб с OP482 была разница, там надо все колошматить. В драйвере 140филипсы, по питанию FC,1nF пленку, кондер 470мкф Elna Cerafine или Nichicon KZ, или тот же FC, ток покоя 35mV. Жаль что автор кита не рассчитал места под 470мкф, чтоб народ поиграл с кондерами, т.к туда Nichicon KZ не впихнешь.

Пробовал я поставить 35mV разницы не заметил (может мало слушал)
зато греется сильнее. Поставил 15mV

Неа, этот вариант явно не подходит, куча разбухшего баса и киношная середина. Пока что BD140 от Philips вне конкуренции, ударники такие как будто медведь бегает по квартире, партия РН56 для более облегченного баса но с более широкой сценой, РН62 для более жирного-тяжелого баса, сцена тёмная, для рок музыки и дип-хаус то что надо.
На двухполосных полочниках разницы особо не ощущаешь, тест проводил на крупных трехполосниках Canton.

Hello friends! Firstly, I must say I'm sorry that I write in english, but I can't write in russian, though I can read and understand what you're saying (I am bulgarian)

I have destiny first edition and your observation on its downsides is quite interesting to me. Especially the case with the q9 transistors. Both transistors in my amp are stuck in a hole in the heatsink itself. They are thermo sensors as far as I know, right? And they don't get in touch with those plastic clamps. Or are there any other transistors that need to be pinned to the heatsink.
Let me tell you something funny - when I got home after getting the amp from the local creek dealer, one of the channels wasn't working properly. I opened the hood and what did I see - one of these transistors was out of the heatsink. Anyway I thrusted it back in the heatsink. Transport fault...maybe
Anyway - my question is: where is the right location for these transistors and are they the ones that these plastic clamps are ment to hold tight?
Thanks!

Hi, what model of amplifier Сreek are we talking about?
If Creek Destiny 1 - please see foto : https://hi-fi-forum.net/forum/thread-436...pid3666112
P.S. This is a Ukrainian forum, we speak Ukrainian, English, German and Russian.

Thanks for your answer!
Yes, my amp is Destiny 1, but I can't see in the photos if these transistors are placed in the heatsinks or they pass through the heatsink and then they are pinned to it by the plastic clamps.
I'm not sure if they are placed in the right spot in my amp.
It was old stock in the shop, it has been given for demo, etc. and I'm not sure if someone didn't make a mess inside the amp meanwhile.
Best regards!

Can you take a photo of your amplifier inside in 2-3 projections + macrophoto ?
Kind regards !

Sure I will, but I'm coming home on saturday and then I will post photos.
Thanks!

Greetings my colleague from Bulgaria.
I have an amplifier Destiny 2. After his purchase, I opened it to check the IDLE current.
This value is indicated inside the amplifier and is very important for its correct operation.
Transistors that provide a constant current value are pressed against the radiator by plastic clips.
These clips are weakened with time and the transistor loses contact with the radiator.
I highly recommend to replace the clips with special iron, which are used in various electronic modules.
So I did in my amp.

Also of course I replaced a few electrolytic capacitors, problematic in your version of the device

Thank you Stich!
I can't wait to get home and check it out. I will provide photos as well.
Cheers!

You are welcome!
only be careful with him, the amplifier is very cranky in repair and requires a professional approach

Here is picture of my destiny:
   

I have checked the plastic clips and they seem OK, but I will keep eye on them when I clean the dust from inside the amp's chasis. My initial question was about the right positioning of the thermal transistors in the heatsinks. As you can see on the picture, they are in touch with the q13 and q113 that are pressed by the plastic clips. Is that OK or they should be separated?
   

And yes I checked the idle current, it should be 21,5mV as indicated. Well, one channel was about 19mV and the other just 9mV

honestly, do not remember how it is decided in my amplifier, but transistors and thermistors should have the best contact with the radiator.
I think it's understandable.
Plastic clips for this task are not very suitable, I do not understand what the manufacturer wanted to save... 5-cent?
I have been repairing electronic devices of various cost and complexity for many years, but I have not yet met with such savings.

Yes, I see what you mean Stitch.
But on the other hand I think they were after some non-thermo conductive material and upon closer inspection I think these clips are made from bakelite. Anyway, those transistors should contact well with the radiators indeed.
Best regards!

the clips that I took from my amplifier lost their shape and were made of simple plastic that changed shape under the influence of heat, I checked it, it's not bakelite.
You can do with your amplifier what you think is right
Regards!
