Hi all,
so I discovered this week that Voice 4 on my Xpander has died and is skipping when playing.
I don't believe its a dead voice chip as I switched the chips and couldn't replicate the issue on the switched voice channel.
Both OSC and PW are failing the auto tune.
So from the research i've studied online I could also try the following:
Replace the capacitor at C449 as this seems to be a common capacitor that dies.
This would be a 2.2 uF polarized electrolytic capacitor with a 50 VDC rating.
And then recap further caps on that voice and the power supply.
(I'm pretty sure that the power supply was recapped by a tech a couple of years ago though)
I could also try replacing the D4051BC chips on that voice.
I'm ok with a soldering iron but not by any means a qualified tech so I want to make sure i'm buying the correct capacitors, a local store sells this product:

Would that be ok to use to replace the C449 capacitor? It seems like its the correct voltage and value but it doesn't say if its polarized. Also how many of these should I buy if I need to start replacing other capacitors on the voice channel?
any advice greatly appreciated?
