I reckon it's worth spending a fairly modest amount of money to get a fully built Hedghog from Stephen (Freya) in Cornwall.
Thank goodness Frank in Ireland designed the Hedghog, now that Darryl has stopped making the Aurora. Both are excellent turnkey solutions to providing signals for 405 line TVs. Both use the Motorola (later Freescale, then NXP) MC44BS373 modulator chips. These had been declared obsolete some years ago but supplies seem to be still available.
