HI
Sooner or later the neon lights will fail. The book Color Servicing made easy by Lemons and Babcoke Pages 117 to 118 explain in details how to change the circuit. I did it to my and works perfect.
The R 741 is one the parts that needs to be replaced to1.2 mg
Use 220K 1 watt instead of neon lights. The 3.3 meg to band pass change to4.7 to5.6meg.
If you need copy of the pages let me know I will fax then to you .
Weak color is associated to the neon bulbs too.
