Ts18 verticle problem

[timmy]

There are 2 10meg resistors that I changed at the 6sl7 and put in 2 1meg resistors mistakenly , and some how I have verticle hold close to maxed on one end but the vert size is almost maxed to fill the most of the screen. So I'm wondering if because I'm using ceramic disc caps instead of tubular could this be messing up the verticle and size because there is not enough capacity. And the wrong resistors I put in maybe they accidentally made the wrong caps work. Because these sets are known to work with disc caps mine seems to be the exception to other sets like this one.
