Help…U67

[Moses Dmj]

hello all,


I´m having trouble doing myself a repair on my u67.
i need to replace the electrolytic output coupling capacitor c9, the on in there is 0.5 uf 350v but i dont´t seem to find one anywere.
i allready posted on the blackmaket regarding this, Axel was kind enough to give me an idea of a substitute(evox/rifa) but it does not fit in there.

does anyone has experience with recaping u67´s?
Wich one is the best modern substitute?

thank you

all the best,

The best thing is to show a photo of what the space situation looks like. There are electrolytic capacitors in this size; it may also be useful to use a film capacitor here. These will last almost forever.

Some physical measurements of the maximum size that might fit in there, would also be useful. Or, well, that's an understatement - it's more like essential.

C9 is 0.5uF/250V - not 350V

there should easily be room for this - and even for a film capacitor rated like this..

If I'm not mistaken Neumann used a Ero/Vishay MKT cap in the reissue, it should fit the old one I guess

Ero/Vishay MKT

Yes, these or similar caps are guaranteed to be available in the right size

I use a similiar size (1uF 100V but there are 250V versions, too) in my S12 test build.

 

[tomas.borgstrom]

There are several 0,47uF axial film capacitors that will fit but it's tight and a bit tricky to install it.

In some revisions there was 1uf/250v so I used Vishay 30D105M250BA2A for the repair. Fits nice, there is just 7-8mm space between PCB's
