That's a good move - capacitor-technology has moved on a lot in the 50-decades since your 840C was built.

Reworked, to eliminate the drifty-resistors and leaky-capacitors, the Eddystone 840x radios can be fun. OK, they've only got 4 IF tuned-circuits so they will never beat the likes of an AR88 when it comes to listening to amateur SSB stations... and the way they shift half-a-Kilohertz when you adjust the RF-Gain control is annoying - but they're really fun receivers to play with.

And they have a good built-in loudspeaker - so they're fun to go listening on the 6.1-6.3MHz sunday-morning free-radio channels! so you can re-create the 'fiddly tuning' memories of the 1960s pirate-stations.
