Emission Labs PX4 Mesh - UX4 Base (Pair)

This is a special order item.  Typical delivery time is 4-8 weeks from time of order.

Since the historical data sheet gives no numerical value for Gm and Rp under normal bias conditions, the values for Gm and Rp were extracted from the historical tube curves.
