FM chip aging issues ???

[madox]

Hi,

I am interested in making a MBFM synth, and was just wondering if people have had any issues with old chips pulled from sounds cards? Have they proven to be reliable, and is the sound quality generally as good as unused chips? Does anyone have experience using both new (old stock, presumably) and second hand chips pulled from old sound cards?

P.S.

Love this site. Love the MBFM demos, and all the other kit here too. A truly amazing contribution to the electro diy community. Thank you so much TK. I was a member here a few years back, when I built a midi filter. Works brilliantly, and it solved some major problems I was having.

Edit - OK, so as there has been no reply to this message, I will just assume that no one has had any problems with old chips.  Please correct me if I'm wrong.
