TDA bunu devreyi ilk bulduğumda bende sormuştum.yanılmıyorsam ( başlığı aradım tekrar ama bulamadım
) fixxxer demiştiki besleme kondansatörleri 4700mf olanlar dirençle kısa devre edilip desarj olması sağlandığı için bu adı aldığını sölemişti.farklı bi anlamda kullanılmış olmalıdır diye düşündüm.su açıklamaları buldum snubberized hakkında iyi çevirecek kişilerden sağlıklı bi açıklama gelir heralde...Carlosfm demişki :
"Lately I've been thinking...
Why the hell don't these chips like high capacitance?
Why do they sound bad?
The reason is so simple that in the end I just wanna kick myself.
Bigger caps have higher inductance, and the amp will have lower damping factor at mid/high fequencies.
The thing is: these chips are really sensitive to this.
Go higher than 1500uf per rail/chip and you start noticing that the midband and treble magic goes away.
The more capacitance you add, the worse it sounds.
The solution is...
A snubber.
I've been testing tonight on my main system, with a new LM4780 amp that is in' in for 3 days on my bench, and it really works.
The original unregulated test PSU ended at C5/C6 on my schematic.
For some time ago - since I tested and use regulated PSUs - that I use 100uf on the chip's PSU pins (not 1,000~1,500uf), and as I reported off-topic on another thread, this works better even with unregulated PSU.
I tested adding to the PSU on the schematic 10,000uf (after C5/C6) and it sounded bad, as usual, but then I tested several snubber values until I settled with this.
It sounded better and better as I lowered the value of C9/C10, the resistors were always 1R.
This is preliminary, more and more tests can be made, but I don't feel that going to a much lower value for C9/C10 will improve things even further.
This is very old stuff, I'm surprized nobody ever tested this with chip amps, or had an explanation for these chips prefering low capacitance...
Here's the schematic, have fun."
