Would anybody like a tutorial (with part numbers) on how to put together a one piece 1/4" (6.3mm) headphone impedance adaptor? (cable free) Looks like this when it's finished: All the best, Mike.

2 questions that show just what a 'dunderheid' I am . . . 1. What is an impedance adaptor? 2. Why would I need one?

Answers: 1. You are not worthy of knowing. 2. Not your decision, but ours.

2 questions that show just what a 'dunderheid' I am . . . 1. What is an impedance adaptor? 2. Why would I need one? Not all headphones like low impedance amplifiers so, for example, let's say your amp's output impedance is 10 ohms and your headphones sound better with a 120 ohm output..... you can make up an adaptor with two 110 ohm series resistors to make the OP 120 ohms. Of course, you can simply fit a 120 ohm resistor in the amp itself BUT let's say you have more than one pair of headphones and some of them sound better with a low impedance output.... you can see how handy having a few impedance adaptors kicking about can be Jan Meier explains it well: www.meier-audio.homepage.t-online.de/tipstricks.htm

Was it expensive? i guess it was yes. i think i paid around £50 inc shipping from US for the cable free one, and a bit more for the custom built one. btw i think one of the HP jacks on my panda may be faulty, if i move my cable i can lose a channel. oddly this only happens if the jack is pushed fully in. if i pull it out slightly it seems fine. i am considering changing them for the locking type. would you say they would be better than the ones fitted? (apart from the fact that they wont look as nice)

(apart from the fact that they wont look as nice) Probe inside the socket with a suitable tool ( a flat blade screwdriver ) and push the prong inward so it makes a better contact with the Jack.... a 5 second fix but hard to capture on camera...... you are basically looking to bring the "prong" inwards so the contact with the jack is more secure.....

I'm sure it would be a very handy reference for peeps both present and future. How hard would it be to have very compact dial-up-your-resistance jobby?! Mini rotary selector, stepped resistors or is that ladder, I mean each resistance adding to the previous(s) in the chain. There's always some bar steward making things more complicated....

Hi Mike
I’ve been using a number of cabled versions for experimenting with but your one looks so much more elegant.
Yes please for the tutorial.
Take care
