I just bought a DP 62L off eBay. Took a pretty big flyer on it. Was sold by the Salvation Army (probably not tt experts) and was described as "working." Anyway, got it in and it works beautifully and sounds absolutely fantastic. I could not be happier with it. Is there any preventative maintenance that should be done? I read a lot on here that the capacitors should be recapped or they could fail and ruin tt. I know absolutely nothing about electronics. If this, or anything else, needs to be done is there anyone that is recommended that I can ship it to for repairs? New guy here and really enjoy the forum. Thanks.
