Amplifier Bias Probes, Any recomendations?

Well I have an Egnater Mod 50 and its time to start tweaking away. I've been very happy with the tone with the NOS 5881's but I want to try some different tubes out. This amp will take 5881, 6l6, 6550, el34, 6v6 tubes and it has the quick bias jacks in the back. So all I should need is a tester.

Added what tubes this amp will execpt.

If it has the bias jacks, any volt meter should work. I've had a lot of luck with Fluke meters, but anything that measures DC volts (millivolt range) should be fine.

Picked up a digital multimeter with probes at the neighborhood Radioshack.

Well, hell i'm in buisness then. I'll pick me up some tubes tomorrow ans start a swapping.

the quick bias are nice, but I still prefer using an actual bias probe. What the test points usually measure is NGV, which is nice, but it doesn't give you an accurate reading of what the static dissipation of the tubes are, which varies from tube to tube in these days of "post NOS" tubes. Plate voltage and current are the only real way to tell how much juice they are getting.

True, but that particular amp is using 1 ohm cathode resistors to measure total current. Other than some minor grid current leakage, those are pretty accurate.

Staying the course then? I'm going tonight to get my leads. Hope to swap some 6v6's in this weekend.
