Hi Andre,
Tergantung kamu sendiri. Mau pake PCB bisa, mau langsung juga bisa.
Thanks.

Biasa aja sih, ga ada yang menarik.
Jadi males bahasnya juga. Uda keburu dibongkarin.
Kalo ga males, nanti mau coba p2p-nya, mungkin itu lebih menarik

Thanks.

Hi,
You can always add volume control before the amp, since this volume control will act as passive preamp.

1875 should not need any zobel – I think.

Thanks.

Hi Jimmy,
Adding
1)POT(volume control) before input coupling cap, and
2)zobel at the speaker output
required to change the current parts value?

I’m afraid it will effect the gain, frequency cut-off or cause it to oscillate.

Thanks.

Hi,
Hampir semua chip-amp biasanya Class AB atau bahkan Class D.

Thanks.

[...] job, I prefer to leave my serious listening session for a while. So if you are waiting for my Gainclone Project initial impression, perhaps you must wait a little bit longer. Sorry to say. Also my Duelund CAST [...]

Even 0.1% of Gold on MCap Supreme Silver/Gold solder is enough to make your tin looked shining as Gold.

The rest is our preference.

wow I screwed up my name I made the post above. sorry I had lead on the brain, tin is what I meant not lead. and just saw that this one has a larger amount of silver, but is still only 9% compared to mostly tin, so I would still think that if you scrape off the tin on the lead and leave it like that or perhaps treat with deoxit it would be better. I doi understand the logic though and i’m most certainly not one of these doubting thomas’s

Hi, love the site!!, looks like a great project and I have been looking for ideas for a ridiculous gainclone to use up some spare caps I have around, which were not enough for my builds of late as I only have 2 of each and everything has been balanced lately. I have 2 x VCAP OIMP 3.3uf, 2 x mundorf SIO .67uf (think thats the value), 2 x duelund 3.9uf VSF copper and plenty of blackgates and nichicon KZ.

ridiculous enough?? one thing I did wonder, your method for tinning the chip leads really doesnt make sense to me, even silver/gold solder is mostly lead/tin and only 5% silver MAX (eichmann is 5% and is highest) the leads on the device will be copper under the tin (so I agree with scraping the coating) and copper is far better than lead, in fact I use solderless connections whenever I can because of this.

the best way is solderless or weld with jewelers solder, only some components as it is a very hot process.

regardless I look forward top seeing the finished amp and your impressions of the sound
