Do you have two of them so you can compare a cold and a hot one?

If heat caused it, how about a heat gun to remove it?

Happy Birthday!

weird -- that was the article under the tv writing one. Not sure how that happened. Here's the real one http://www.psfk.com/2013/01/panasonic-electronic-pen-ces.html

Can anyone suggest a large TV/monitor for under $1500? Bigger is better, and absolute picture quality is not critical. This will be used mostly for Power Point presentations. The ability to connect a computer/tablet/phone to it wirelessly would be great, as would the ability to use a "pen" to doodle on it in some way. (Projectors have already been rejected as an option.)

This much I am familiar with. And in essence you are basically saying that a CCS has a high impedance that forms a voltage divider with the load with the lion's share of the current going to the lower impedance portion. Were it practical to do so and if we didn't care about efficiency, an amp with a 100KV supply could use a 10M resistor to much the same effect. I guess the question is that in a common cathode triode, the lowish plate impedance drives the plate load in parallel with the load. A pentode is the opposite and has a Zout that is PS's Zout in series with the resistor load with the tube modulating the PS. So I am wondering if that resistor load on the pentode is a reasonable and somewhat unexplored way to drive these things or if your above calculation contains something to suggest otherwise.

Could you comment on the influence of the plate impedance on your calculations. Or specifically, when the output device itself is a constant current source. Several of the triode based amps all have a lowish impedance. But some of them use a cascode of some sort which would produce more pentode/transistor like plate curves with a very high Z. Does it matter?

Very nice build, Kerry!

As someone whose monthly data usage is in the 100 MB range, I can't wait to dump Verizon.

Next time, look into dd which has always worked for me.

Why don't you have Camexpert drill them if they need to be so precise?

Goodness, Shelly!

Oh, and this. I was a record collector many years ago. Black is common, peach seems to be relatively common, but I've not seen the 1st pressing burgundy swirl very often.
