As a newbie, I cannot understand a lot of abbreviations in a tube data sheet. Can you please help me explain them, how to apply them, which parameters I should pay most attention to:
Vh, Ih, VaMax, PaMax, Cgk, Cak, Cga, Va, Vg1, Ia, Ra, S, Rk, Zout, Pout, THD and etc.
Thanks a lot.

Beyond that, look through the On Line Tube Learning for newbies.... thread.

You need the REST of the tube manual too - there's a list of abbreviations, and much more general information. Get one from eBay - most any one will do, but RCA and Sylvania have more data. Or just read one online... many are listed on my tech page: http://www.audiophool.cjb.net/Techno.html
But here's a start:
Vh- Heater voltage
Ih - heater current
VaMax - maximum plate (anode) voltage
PaMax - maximum plate power dissipation
Cgk capacitance grid-cathode
Cak - " anode-cathode
Cga - " grid-plate
Va Plate voltage
Vg1 - Grid voltage
Ia - plate current
Ra Plate resistance
S - transconductance - measured in Siemens (aka mhos) (inverse of ohms)
Rk - cathode resistor
Zout - output impedance
Pout - Power out
THD - Total Harmonic Distortion

Thanks a lot.
last year I think, there was a series of replies by SY in regards to reading tube data including the curves.
I do not know where it is though. maybe a search on the forums using "SY" on the username.
