E188CC E88CC 6DJ8 ECC88 6922 PHILIPS MATCHED PAIR NOS 2pcs

Gold pins,10000 h,grey anode plates,o geter,tested,with box

The 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 leakage

Note: 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 ... Digital testers can not give the same measurement results as the classical tester for impedance, reactance, capacitance, conductance, the mode power supply - Switching etc .
