Default Dynaco Bias Balance kit

Dynakitparts.com just came out with a upgrade kit for your Dynaco ST-70, Mark II, Mark III and Mark IV that will allow you to balance the bias between the output tubes.

No modification to your chassis is needed for the additional balance pot. I have installed this in my ST-70 and was able to balance the bias between unmatched tubes, which is good as matched tubes when new are no longer matched as time goes on.

Go to http://www.dynakitparts.com/store/product.aspx?id=295 for more info if you are interested about this mod.

Default ? On dynakit bias kit for stereo 70

I just installed this kit and can't get any voltage readings from the front socket. Any thoughts as to what I might look for?
