Icom IC-R70 Bad Reception

[Andilescu]

Hello,
I'm a German SWL and BCL and first time in this forum.
Some days ago I got an ICOM IC-R70 with very weak reception. Additionally the PBT seemed not to work.
I discovered, that the voltages at the bases of the oscillator-transistors Q9 and Q10 were zero.
The reason for this: the Xtal X1 has a leakage to its grounded case. I measured 570 Ohms between one of the pins and the case. I desoldered the grounding wire and the item was fixed.
Does somebody know where to get the 9.4665 MHz Xtal?
Happy 2026!
