E188CC E88CC 6DJ8 ECC88 6922 PHILIPS MATCHED PAIR NOS 2pcsGold pins,10000 h,grey anode plates,o geter,tested,with boxThe Philips Holland SQ E188CC / 7308 Gold Pin is the holy grail of lush 6922 tone. These are right up there with Telefunken CCa and Siemens 7308 when it comes to rarity. To our ears these sound more musical than the Siemens or Telefunken. These have a large round getter and beautiful construction.EXTRA TUBES GREAT SOUND!!!!!!EXTRA MATCHED!!!EXTRA BALANCED!!!All the tubes that were sold worked for 72 hours on the aging device to stabilize and in order to capture the characteristics. otherwise, in practice, some tubes quickly change the characteristics that deviate from the given values of the anode current Ia. there can be a misunderstanding. so the pipes are allowed to work 72 hours in order to get as much to their proper characteristic.They are also tested for gas, short and leakageNote: The measurements were carried out with Neuberger RPM370 saw and guarantee for this measurement. The tester has its technical and electrical characteristics that participate in the activities and measuring tubes. Each tube is a special electric circuit that works in conjunction with the saw and this gives measured values. Power saws with classic rectifier and everything else and it has its own impedance, etc ...

Probably no one in this world has a pair of CCs like this because there are NO more of them !!This version with gold pins is professional and allows work of 10000 hours !!!!It is very difficult to pair 4 tubes and to keep each of them balanced. Before recording the characteristics, all CC tubes are aged for 72 hours in a specially made device and then tested and selected. For these 2 tubes it took over 50 tubes to select a that, you will admit it is very difficult. and theres no need to brag about those tubes - take a look on the net and everything will be clearwhy do I have to age them for 72 hours. Since I give the electrical characteristics of the tubes and for that to be correct, the CC tubes must be forced to work for at least 48 hours in order to equalize the working mode and only then the characteristics are recorded. the current Ia measured on that occasion does not have to be 16 mA and that is 100%, they can be higher and lower, within some limits - there are some on the NET, but it is important that the triodes in the balloon tubes CCa are as uniform as possible . And thats except Ia - mA quality which is primary for me and as a third reference, if I can, give the code .its nice to be harmonized due to the later exploitation of tubes-10000 hours.They are also tested for gas, short and leakageNote: The measurements were carried out with Neuberger RPM370 saw and guarantee for this measurement.
