Sorry if I have to disagree with Paulwp.I took my AR9 pre.to Scan.Waited the week/ they couldn't find/fix the problem. Payed the $40.'twas a tube,I found out latter. Also my Kenwood tuner,no sound R. channel. Paid the $125 repair,got home,tuner now only gets 4/5 stations/and very poorly at that. Bought another tuner for 175 used. Kills my Kenwody.The Kenwood is for sale,but I think the shipping would exceed the value of the tuner. No lies,or streaching facts.
