Well worth making sure the DC restoration of the luminance circuits is in order.
If the black level is wandering about this will have an effect on the colour reproduction. In the Bush CTV25, like other sets such as the Pye CT70 the final summation of the Y signal and the colour difference signals from the R G B amplifiers takes place in the CRT.
