my CTC-90 project.

Quote zeno from other thread about CTC-90.

If its the chassis I am thinking of it was very short lived. No value
except that its different. It was modular with a normal HOT & an
SCR in the power supply. IIRC the last RCA with a delta CRT. Only
saw maybe 10 of them, all 19" come in.
It may also be that fold down monstrosity with ITR's, we all hated them.
On latter sets vert was common problem. Always two 220K ohms &
a transistor.

The module is cleaned now, and the 2 220k res seem OK (r9 r6), that does not mean that I'm not going to replace them, along with the 2 electrolytic capacitors c11/c12 680uf 50v.
I really do not see anything wrong with it.
