Hi, I've acquired a early version of the Ekco RCP (V1 = E???, V2 = EAF41, V3 = ECH21, V4 = EBL21, V5 = 6X4). Does anyone have a schematic plus service notes they can share? Cheers Bruce

Its close, but not quite the right model - I've got the "early version"

Good morning Bruce
Your set would certainly appear to be an early version of the 'Cygnet'. The IF valve (which you show as 'E???' is most likely to be an EF22 (equiv. to a 7B7). Unfortunately, I haven't been able to find a circuit of the particular chassis that you have, although the converter & IF sections are likely to be similar to the earlier (1951) RBG 'Minor'.

Thanks, but again the schematic is for the later model. I've largely restored it (electrically) - replaced all electrolytic and wax caps. Checked all resistors - a couple are about 20% out so will probably replace. Case will clean up - just need to try and do something with the missing label on the front.

Ok, that's interesting that they changed the design that much between versions of valve lineup, I've seen minor changes in other makes e.g cathode bias resistor values to fit the changed valve lineup.
