> A replacement power transformer had been bodged onto 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

> 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

> 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
