Recommend tube meter

You need a DC voltmeter, not a "tube meter.". Radio Shack has them. Ask them for a DVM or a multimeter. It will be able to measure AC voltage, DC voltage and resistance. Set it to DC volts and you are in business.

Thanks.

My little Radio Shack digital multiple meter is easy to use. It cost about 50 bucks a few years ago.

They also have traditional devices with analog gauges/displays which are very cool looking but tough to read without enhanced training;-)

IMHO, for this application, you can simply get a multimeter from Radio Shack or Sears. I have been happy with Fluke and HP products, but if this is your only use of it, I recommend getting something inexpensive. There is not much to be gained by purchasing and expensive multimeter for tube biasing only.
