Thanks for the confirmation that it's ok, even encouraged,
to place FS's on the list!  So, here goes...

I have a very nice GPR-90 for sale, Canadian manufacture, 
s/n 3092.  Here's its situation:

Bought the radio at a hamfest, and it was in saaaad shape.
A replacement power transformer had been bodged onto the
chassis, the BFO coil was AWOL, rusty case, dirty..  Over the
course of a couple of months I went through the radio pretty
thoroughly, wound a new BFO coil (got to use my Morris Coil
Winder in anger!), wrote up a spec for the transformer and
commissioned its construction at Peter Dahl, did a complete
alignment, including resoldering those nasty ground busbars
in the RF section, had the case powder coated, replaced caps,
tubes, etc, etc.

Anyhow, the radio now looks very, very nice, maybe a 9/10, and
it hears very well indeed, meeting or exceeding sensitivity specs.

To summarize:

* Powder-coated case
* New Peter Dahl power transformer
* Rewound BFO coil 
* Recapped (all papers and small electrolytics) and retubed
* Filter cap reformed (< 50uA at 450V, each section)
* Mechanicals completely dissassembled, cleaned and lubed
* Complete alignment
* Includes a manual copy

The radio's been tested fairly extensively, including operation
with an MSR.  Pictures at

I'd like $850 + shipping for the radio, which I think is fair given the
amount of effort expended on it.  I will ship, but would obviously
prefer pickup in Chapel Hill, NC.  If the radio gets shipped, the
new owner will probably have to realign the RF front end, given
the relative fragility of the circuitry.  For an additional $75
I'll construct a custom wooden crate for shipping.

Let me know if you're interested.  If there are no queries from
the list in the next couple of days, I'll put it on EBAY.
