  Oh, please stop offering to explain things, it's hard to see it as genuine, the impression is more one of intent to be patronising and insulting.   Cheers, w

  OK, firstly, with regard to cable geometries and impedance, you prove my point precisely.   You twisted the lamp cable, the impedance changed. 6 turns per foot is trivial to achieve by accident, twisted pair is...

  Quote: Originally Posted by jnjn  4.  ABX is flawed whenever a switchbox is used.  Changes in the system caused by even putting the box in renders comparisons meaningless.  This is from EMC...

If I wanted reserve power for my phone or headamp, I'd use duplicates of the batteries that are already in there.   The energy density of Lithium batteries is the best available. It's inaccurate to characterize them as 'a...

Even a cheap socket should work at any angle when new.   When an amp has to be held at a particular angle to make it work, this often indicates a poor solder joint.   Soldering is straightforward, but if you are...

You need a dual-pole switch to break the connections from both batteries. You can leave the ground connection unbroken, but you must switch both the positive and the negative connections. A dual-pole switch is 2 switches built in the...
