Default Re: HMV 900 TV restoration.

From what I can see some of the 240 line circuitry is still in place. There are wires cut all over the place and lots of caps have been replaced with non standard types possibly in the late 40's and 50's.
What I really could do with is an original manual with the 240 & 405 line circuitry and some hi resolution pictures of a restored set, this would help me out with snipped out wires and components. I have checked out all the tuned circuits and they "look" in nice condition, not even a spiders skeleton inside!
There is a lot to be done though as there are so many wrong caps and a goodly few paralleled up resistors.
