Looking for advice on retubing a late 70's SVT. Purchased 2 years ago, not sure about it's history. There is at least 1 mismatched power tube and now the amp has a problem and makes bad crackling noises and one of the tubes glows really bright. Been wanting to retube and get a fresh start for awhile now. I am looking at these complete tube sets cause I was interested in getting NOS where I could. I'm not too particular when it comes to "this tube sounds like this or that", just want well known reliable and well liked tubes. Also, I've bought from Eruotubes before for a guitar amp, super nice dude but wasn't that into the JJ's. Anyone want to put in their 2 cents or know of other tube sets available? http://www.fliptops.net/catalog/product_info.php?cPath=24_64&products_id=363 http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&ssPageName=STRK:MEWAX:IT&item=160203141909 Thanks!
