Help needed,Re-Cap- Electrocompaniet AW250-DMB-R

Help needed with Re-Cap my Electrocompaniet AW250-DMB-R.

I wish to recap little eletrolytics and film capacitors.

What type or kind is best for this?

master board:
C1=470K100
C4=1NK100
C17,C18,C19,C20,C22= .22K63
sister board C603= .22K63
All these caps is S&M metal polypropylene.

All little electrolytics is Elna RE series.

The fact that you even have to ask for advice tells me that you have no idea what kind of minefield you are entering. This is a extremely difficult amp to tinker with. Please please don`t do it.

You have been warned.

If it works, keep it working by leaving it as-is.

I forgot to mention that there is a problem with the high tones, as if they come with little interference(like a dirty) and the warmer the amplifier gets, the more you can hear it.I hear it ,but my family not hear this.
I measured amplifier with Rew and Creative sonud card,but nothing found in measurement tests.

Has it been sitting unused for a long time?
If so, let it burn in with a few weeks of regular use.

 

[Vortex666]

No,every week I use it.

Sounds kinda like crossover distortion. Have you checked the bias?
Did you measure at low power?

 

[Vortex666]

Bias is 13mV like EC support told me,they gave me little adjusting tutorial.

This is an expensive amplifier, not sure I'd have the guts to delve into it myself.

I can change components,all relays allready replaced 2 years ago.
Question is,What brand and type of components could be put in there instead of the originals?

Before you start exchanging parts, solve the problem with distortion. Otherwise you are embarking on a rather long way.
