Armstrong 224

[catch29]

Hi. I've got myself the above tuner (no decoder) and need a wiring diagram or at least a valve plan to get it running, can anyone help?

A bit on it here: https://www.radios-tv.co.uk/community/am...c-circuit/

Manual does exist

I think the 223 also includes AM, basically by second IFT on each valve and 224 is FM only, so the 1st link is 224 FM only IF & detector and the 223 Schematic has the VHF section and PSU and extra AM bits.
