Ok you tube "experts"..
Getting ready to review the Vali 3.
I ran across some info on the "ECC42" tube family...
Like there is none???
From a diy site:
The Russian 6N3P dual triode is often listed as ECC42 equivalent. I searched everywhere for ECC42 datasheets. Could not find any. Did that tube really exist at some time?
Reply:
Not ECC42 but 6CC42 or 2C51 equivalent.
gm = 5.5 mA/V and mu = 35
Cheers,
Reply 2:
Those listed as equivalents appear to be noval B9A based (9 pins), but an ECC42 would have been Rimlock (8 pins). I conclude that the ECC42 never existed. Possibly someone somewhere thought that the 6CC42 in the East implied the existence of an ECC42 in the West?
So was there or is there a ECC42 family or is it 6CC42 ?

Pix: Notice the 6N3p's are referenced with the 6CC42 vs ECC42.
