FS: Matched Pair Sylvania Gold Brand Black Plate 5751 Tubes

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.
