[time-nuts] HP58504A antenna

[Jose Manuel]

Hello all,

I´d like to repair a HP58504A antenna that don´t deliver any output signal. The current is about 30 mA ( I think too high), and the transistor (unknown type) and the MMIC (uPC2749TB), seems to be with correct voltage.

Does anyone have any experience or data about this antenna?

I took an inside photo: http://www.ea1px.es/HP58504A.jpg     Can the transistor be identified by the color code?



Thanks in advance, José, EA1PX
