Default Re: Coming soon: 405 colour on my Pye CTV

A replacement luma delay line has been fitted and now the chroma and luminance are coincident.
The original delay line had failed during the previous ownership. The replacement part was removed from a BRC 3000 CTV.
The original delay line is 59cm long, the replacement is only 14cm long.
The luma delay driver is a PL83 video pentode, no puny BC108 transistors in this set.
