Noise from new caps in signal path, please help!

[rg12]

Today i got the caps for my whole amp (recapping the whole Pioneer SA-7300).

I started with the two power caps 10,000uF, and everything went smooth, and sound check is great.

After the power caps i moved on to four caps in the signal path
(all are(were) 2.2uF 25v Tantalum cap).

I replaced these four with Mundorf MKP Metal Polypropylene (They
are ofcourse Non Polarized).

Did the sound check and now i get an irritating uneven buzz and hiss
and some weird changing noises.

I tested a few songs anyway and when the volume is up i can't hear
the noise much and there is a great improvement in sound exce[t for the
noise.

I noticed that if i put my finger close to one of the four caps, it increases
one of the noises being created from the new caps. Does that mean
anything? or it's just a static thing?

Please help!

me would limit capacitor upgrade to replacements that fit into the pcb. Otherwise you may get an unwanted antenna.

Antenna? isn't there a way to work through that anyway?

So i guess i have to put in those tantalums again...damn...

if you can exclude bad solder joints and accidentally miswiring, there is not much room for speculation.

Problem solved, stupid me, the second sound test was with the laptop's
power adapter and not running on batteries and thats what creates the
interference.

so the 'old' amp had this problem with your laptop too?

Yes, i usually connect it without the power adapter when playing music.
