Anyone in Australia with a curve tracer willing to trace plate curves for a 6336?

Hi all,

I'm Hamilton based. Coincidentally, I will be in Brisbane on Thursday for 1 day.

My uTracer is a 3+
Anode and Screen suppliers 400v
Current range 200mA
Grid Supply -50v

I don't know anything about THE 6336. Will the above specs be sufficient?

The alternative is you do it all manually on a valve tester like an Avo.

Let me know

Andrew
 
Beware the 5 amp heater. Tube testers that I know of will be very unhappy at any attempt to warm up a 6336.
An alternative might be to make a jig with some adjustable power supplies and plot from data points by hand.
Worth trying if you want to simulate what the tube will do at a preferred operating point, and FYI these tubes have pretty terrible sample to sample variation (I have some).
