I've used black ink (like what you use with quill pens) diluted with alcohol to do this. Worked really well.

Why do you insist on using 2N transistors? These are almost never a good choice in an audio amp such as your Sony. These transistors are usually used in power supplies.

You should be able to disconnect the tweeter without soldering. I had the same problem on these speakers and fudging with the tweeter fixed it.

The first "peg" on the meter is at 1 watt of power, and even then, the movement is very subtle. Now, 1 watt is a LOT of power, rarely will you play that loud (unless you have really inefficient speakers, which is not common). For this reason, the meters on this receiver are largely useless. On...

"Most sellers in China are just as honest" is just a plain lie. OK, they may be honest, but their sources aren't. The fact of the matter is, 100% of the parts you buy from China are fake. The margin of error to this statement is so small that it becomes 0% in the grand scheme of things. If you...

Unless you REALLY need those speakers, there is usually way too much effort required to do this. And the chances of it failing spectacularly are way higher than success.

Or Bitcoin... These models are quite failure-prone, so if you're not a tech, or don't want to spend the money (100s) to get them repaired, definitely keep away.

Dudes, don't be naïve. Fake components are being made, regardless of price. I've come across dozens of fake TO-92 transistors, and these are worthless! There are certainly tons of fakes of these being made. These parts are relatively expensive, making them a very attractive target for fakers.

Leave the caps alone. Replacing them can do no good in this case.

Definitely necessary on the 1020. The board gets smoked, and takes the surrounding components with it.

And what happens if there's an accident involving your home made amplifier?

Don't bother with the stock config. Go EFB right away, everything else is pointless. Also destructive to your tubes.

Don't do the above. Replace only. This is playing with fire!

I hope you mouth people are kidding. If not, stop that. It's unhealthy and dumb. It makes you dumber, too, and since you're already dumb, who knows what'll happen?

No, I've had them all and I fully restore all amps before listening to them. Total duds.
