So, if I have some Cardas non-Pb eutectic solder, and I want to use the HE-adapter only with the HE-6 on a tube amp with 4wpc on an 8ohm tap, which resistors should I use? Mills and Shinkoh? Dueland? Audio Note?
it best to match 8 ohms for an 8 ohm speaker tap? So how about simply removing the series 25R 1/4w piece? then the total is 8.3R instead of 8.8, and there's nothing extra in the signal path.
solder dosnt matter, if you have a tube amp your gonna want some nice allen bradley carbon resistors (the audio not tantalums are good also) no ww or metal film for the ones in series.
for the 2 in parallel somthing above 8 ohms is better (matching dosnt matter this is all off of the 8ohm tap of your amp) i use 10 to 16 ohm resistors in parallel but they should be of high w disapation i use 20w resistors, the ones in series dont matter as much for w dissapation id say above 1/2 w is fine.
so in all together for you amp id use 10 or 16 ohm resistors 20w in parallel, then for the ones in parallel depending on the gain of your amp and how much surface noise there is maybe around 36ohms or 56ohms or 100ohms depending how much hum and other noise are in the amp by itself the higher value the quiter everthing any of these should be atleast 1/2w.(most speaker amps have a bit of hum just due to the fact they wernt designed for headphone use and you dont hear the hum on speakers)
your idea of less things in the signal path wont help you much if you wanted the least stuff in your signal path just run your headphone straight into the taps of your amp, this adapter isnt required it just adjusts many of the things so its more suitable for headphone use.
for example i made one of these for my 2a3/45 tube amp i used 16ohm 20w resistors in parallel and in series i used 100ohm resistors. sounds amazing from my hifimans and my lcd-3.
if you have any more questions just pm me
