[R-390] Looking for a 5-25 pF Trimmer

[Barry Scott]

I ran through the RF Deck alignment last night and discovered that the 5-25
pF trimmer in Z203 has a dead spot.  I pulled that can and opened it up and
found a section of the center ceramic wafer is broken and floating around
inside the can.

Anyone know where I can find a replacement trimmer or, perhaps, just the
parts that I can rebuild it easily?  I don't exactly need the entire
trimmer but that would work as well.

For reference: https://talonelectronics.com/shop/item.aspx?itemid=6535

I found one on Surplus Sales of Nebraska's website and I think that will
work; however, they list them as "Tucsonix" brand (I think perhaps that
should be "Tusonix"?) so was wondering if this is indeed an exact
replacement (so I can just unclip the spindle and steal the washer and use
the new top if I want to).  I was thinking the originals were Erie but I
don't know for sure.

I've looked and haven't found one in this form-factor elsewhere so thought
I'd ask here.

Thanks,
