I recently bought this really nice rare NOS Telefunken CCa E88CC (Made in Ulm, Germany in late 1960) tube listed here: http://www.ebay.com/itm/112274223423 The triodes match well and it is new old stock. I have not even installed I have decided to go a different direction in tubes so this tube needs to go. I want $162 plus shipping for it. PM me for more details or if you are interested in buying it. Thanks!
