6DJ8 = ECC88 != 6N1P
After checking out 10 off 6N1P and a pair of PCC88s in my test rig it
seems these tubes are not really as similar as I thought.
All 10 6N1Ps recorded an plate voltage between 140 and 150V and a
cathode voltage between 2.5 and 2.7 volts.
The two PCC88s read from 101 to 125V plate volts and 2.85 to 3.25V
across the cathodes.
OK this is not a definitive test but the 6N1Ps were very consistent and
very close within a tube. The PCC88s seem to be all over the place even
within a tube.
I conluce the Russian 6N1Ps are good and the pair of Miniwatt PCC88s are
skip material.
Thoughts anyone?
Cheers
Ian
