redgum Posted January 1, 2020 Posted January 1, 2020 (edited) Item: One matched pair Sylvania Gold Brand Triple Mica Black Plates and Sylvania JHS Gold Label Triple Mica Black Plates with 45 Degree Angled Square Getters, 1960's. Location: Port Macquarie NSW. Price: $110 Postage Included. Item Condition: Good. Reason for selling: NLR as have a new amp on the way and doesn't use 5751 tubes. Payment Method: Pickup - Cash, Paypal, COD Only, Direct Deposit. Extra Info: These tubes sound great and were the best sounding pair in my amp at the time. I have used these for 40 hours without any problems. Both tubes are the same and manufactured in the same factory. Tubes are balanced from plate to plate. TV-7/U Test Results: Gold Brand Tube: 43/41. Gm: 1075/1025. JHS Tube: 42/42. Gm: 1050/1050. I have handled these with care. Plenty of lifetime left in these pair. I wouldn't be surprised if they outlasted a pair of new production tubes.
