Series: more voltage, same runtime. Parallel: more runtime, same voltage. all those 9V tricks will work, to more or less effect. end result: you still gotta carry the thing, and the battery pack. Stick to your TA.

Hmm, you'll have to do a bit more reverse engineering than that. It could be some are single amps, some are duals... they look the same unless you know. Might not even be related to the headphone circuit. The easiest way to know is...

SSOPs. Right at my limit. I can touch the individual pins with the 1mm tip and I only reflow the pins to either side when heating one, and I guess I could be successful. Double the density of SOICs? Ugh. And you like this? Woah. I never...

That's great, as an inspection tool... not as a work tool. (probably makes stones look good too, whip out the loupe with a florish and check out the teach's wedding ring!) Like, it'd be GREAT for seeing all the pins bridged together...

No, not mono/stereo... but a switch. Those "horseshoes" are only a short with no plug inserted... Divie's right, you were floating the phones ungrounded, by wiring the ground wire to the side that got unswitched when the plug...

While only marginally related (the link is in the gallery section of passdiy) THIS is what I wish I was cool like. THIS is what I would do if I had a garage or basement workshop. I hate speakers... I'm headphones 101% of the time...

No, that's probably not it. If the 'lytics were hosed, then running the amp without em would make it work just fine. You don't need reserve caps when a BUF634 is your rail splitter! If removing them makes it louder, it's probably...

Ok, so no one has a suggestion for you. Stop bumping it. Do you want portable or AC, glass or solid state? Do you want something that is paint-by-numbers or something where you have to think? Do you want to do math or want the math...

Let the crossposting continue! I answered you at the other place, sorry.

Well, that's not entirely true. Sometimes a part is also made by someone else, later in life. But usually the entire part # will be the same, even if it's not their normal nomenclature. Like, many people make LM317-Ts, not just...
