RFT Saalburg 5170C radio (Techniek Radio/TV)

Hi. I am presently working on my RFT Saalburg 5170C radio (ex GDR 1962)and I am having some difficulty in getting reception again on ukw, and a.m bands. The tubes light up ok, voltages correct. One thing that I have noticed is that if you apply a test probe to the g1 terminal of ECH81, it acts like an aerial, so thinking that the ferrite aerial coils were o/c I tested them, but they proved to be ok.
There is no ukw reception either, but there is some life in the output stage when the centre tap of the volume control is pressed.
Has anyone had experience on these radios? I can not see any breaks in circuit.
Regards
Mike (U.K)
