Dave,

Just what gave you the idea that changing low level vertical processing components will fix an obvious vertical output defect? What got into you, man?!!! ;-)

A) Change the electros related to the "vertical output", pump up diode/electro, derived supply filter electro/rectifier, output electro, and check the solder at the yoke socket, vert output.

B) Read the faq.

Thanks for your reply So far I have changed C308 2.2uF, C315 100uF 100V, and possibly C409

Thanks again Spooky

In some oler Toshibas with vertical problems there are 2 2.2uF capacitors, both being red or brown, and one being a bit removed from the actual vertical deflection circuitry.
