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 .
