I have 4 pairs of 5687 Tubes for sale. All were tested in my Modwright SWL 9.0 Preamp. I sold my Modwright and do not need these anymore. Now is your chance to do some tube rolling and not break the bank.
1 Pair of Kuhl-Tube Cryo treated GE JAN 5687wb tubes,
1 Pair of Tung-Sol Bronze Plates marked JTL 5687
1 Pair of Tung-Sol Black Plates marked National 5687
1 Pair of USA made Tung-Sol Black Plates marked Raytheon 5687 WB.
They were all just tested by T&C Tubes and all tested "Good" to "New".
All Tubes have just a few hours of burn time under my ownership. I will sell all 8 tubes for $100 OBO plus shipping. I will take PayPal with no fee.
