IIRC the Bandspread versions of the coils looked like normal ones, but you could screw a screw into a hole to change the range for wider coverage of the amateur bands

Sadly I sold my HRO complete with all coil packs (including bandspread) when I moved here 12 years ago, and my AR88 and several other receivers and LOADs of test equipment including two Avo CT160 valve testers  :bang:

'cos we made things PROPER in those days  :lol:

I presume that doesn't include Hunts caps. ???   :zap:   :bugeye:   :(

Like your RA17 BTW.  Had them in the RAF  I had a HRO at one time. Maybe I should have kept it. Worked fine when I sold it for 5.   :scratch:

This installation has been working fine.

Alternative to magnetic scales video here - glass scales:


Incidently, pretty much same locations and logic with this video and my installation.

How is it that the capacitors in these old PSU's can last 60 years but modern caps die off after a few years especially if they are not used?
