I have the following matched quads for sale or trade left over from prior tube rolling. I'm interested in any trades for NOS EL34 or anything else interesting (cables, etc.). All of these have the same internal structure so matching is both electrical and physical.
1) Sylvania 5932 dual black plate. Original boxes, bought NOS from Silk Electronics, less than 100 hours usage. These are killer tubes and a rare find. They are among the best in the 6L6 family, including 350B and EL37. I won't feel bad if these don't sell. Three tubes are from the same date code (9/52) and the fourth is from 6/52. Asking $150 for the quad. Specs:
70 mA / 6100
75 mA / 6100
72 mA / 6100
70 mA / 6200
2) RCA 6L6GB. Original boxes, black plates, bought NOS from Silk Electronics, less than 50 hours usage. Asking $100 for the quad. Specs:
70 mA / 6100
75 mA / 6100
72 mA / 6100
70 mA / 6200
3. Sylvania 6L6GB. White boxes, bought ANOS from Hamtubes. These also have black plates. I have less than 50 hours on these. Asking $80 for the quad. Specs:
48 mA / 78
44 mA / 75
48 mA / 80
49 mA / 80
4. Svetlana Winged C 6L6GC: matched quad from Tube Depot (21 mA). Less than 200 hours. Asking $40 for the quad
5. Svetlana Winged C EL34: matched quad from Tube Depot (33 mA). Less than 50 hours. Asking $40 for the quad
