S.E.X. amp seconde hand

[Paul Birkeland]

Those are capacitors you removed.  The amp will not pass signal without them.  You should never listen to an amp that doesn't pass its voltage checks.

I see, I have learned enough for one day.  Will never listen to a amp that do not pass the checks! Sorry for that.

Will come back if I have installed the capacitors again. Also thinking about the repair service BH is offering.

there was a very tiny but effective shortcut between the legs of Q2 on the C4S module. This was giving the weird values in measurements.
I do pass the resistance check; and the voltage check now.

Woud like to check first this before I can listen to the amp:
Because I have broken the leg of "0.1uF 630V capacitor" during my inspection I have ordered new ones but those will come in next week. I have come in these ones today:

My question is: can I safely use them until to right ones will arrive?
Have a nice day! Marco.

can I safely use them until to right ones will arrive?

Yes. Since the new caps have the same value and rating (0.1uF and 630V), and are non-polarized, they are interchangeable withe the stock cap.

But note that the caps you linked to are metalized polyester caps. The stock caps are likely metalized polypropylene.  A lot of people believe that polypropylene caps sound better. Assuming you've also ordered a polypropylene cap that is similar or identical to the stock cap, you'll be able to test this for yourself.

cheers, Derek

Thank you Derek! My soldering station is getting hot already
And thanks for the info behind the polyester/polypropylene cap!
