how hard is it to take Aune a part ? I want to take a look and post some picks for you guys 

 

[arcorob]

So in anticipation of some cap swaps (heck why not, I like projects) - ordered these to ensure authenticity - 4 each
 
4x ELNA Capacitor Cerafine Roa 470uF 25V Audio HIFI US$8.00
 
4 x PANASONIC FM 330uF 35V cap LOW ESR AUDIO ELECTROLYTIC CAPACITOR ~~US$4.80
 
Nice selection at headfishop.com

You need a torch and a table saw but after that it is easy...JUST KIDDING...It is easy

  there's no need to change parts if they are working as intended imo. Sure we can start rolling all the parts for better. Might as well start with the conversion chip lol

 
Problem is those secondary caps were not working as intended in mine, and I would be very curious about Coils caps too. They were very low grade no name caps in mine, and looks like in Coils also. The Aune website pics show Nichicon caps in this spot...which obviously not everyone got.
 
Point of all this is the build quality of the Aune T1 is quite nice. Except for those 2 caps, they were skimped on.
 
 
 
Coil,
 
The purple ones in your pics are the ones I am referring to. Yours are even a different value than mine. Yours(470uf 25v). Mine(330uf 35v). Being 220V should not make a difference since the transformer is what steps down the voltage to the same as my 110V unit. Does yours even have a brand on them?
 

Thats weird. Ok, we have established that we have different caps on that spot but to which value should I change? 330uF 35V or 470uF 25V? Which is actual original value? That`s confusing! ;S Again, here are my caps on that spot:


 
 
Can you maybe took better pics from your Aune T1 capacitors on the PCB so I could add them into that fake caps post?
It would be easier to compare for others and me too. Btw, my caps have additional dark brown/purple marking also, didn`t catch it on the pic. Will take my unit apart again later. Have to do some work also besides Aune T1 madness ;D

You can select each from there (depending on your preference) I chose the Panasonic for one and the ELNA for the other
Specifically
ELNA

It would be great if somebody did a DIY guide with pictures showing how to disassemble T1 and change those inferior parts. Arco, lwrs, space, coil... I'm looking at you guys I'll post some pictures as well when I have the time to open my unit.

 

[arcorob]

I am sure someone will beat me to it but just FYI, whenever I do a project like this, I always take pictures and post
 
Like this turntable thread I am doing

will open my unit hopefully tonight again but first going to make ´how to clean tube pins guide´ and test these tubes briefly I got today:

 
They cost me 4£ total, post included ;D PCC189 seems to be relabeled Tungsram PCC189, two different PCC85 (one is Mullard Blackburn) and one PCC89 Mullard from 60` (not sure it`s pin-out is ok to use, got to check). They all seem to be NOS and unused.
 
Edit: checked - PCC89 pinout is different and it requires socket mod. But it should work flawless since it is 7.5V and 300mA.

 

[spacequeen7]

here they are ...any one of them should be replaced ?

 

[lwrs10]

Space, you have the same secondary caps that I do, but your primary supply caps are an offbrand too! In yours I would swap those out for sure!

Was the Aune advertised as having premium caps??

[arcorob]

Spacequeens look good but what are the purple ones ? Also, would you say his ELNA's are knockoff?

 

[CoiL]

spacequeen7, is your unit bought as 110V? You also have same caps on that spot as lwrs10 has. But my caps are different (470uF 25V). Also seems that you have different main power supply caps, we all have them different seems to me (what are your main supply caps values? don`t see it on pic). I`m really interested why we have different values at that secondary power supply caps? And which value should I choose to replace for?!?

the 110 and the 220 version should NOT have different caps. They use the same voltages inside the Aune.

 

[CoiL]

Yeah, but which value is the "correct" one to change for? 330uF 35V or 470uF 25V ? Wonder what caps Salvatore has.
