One thing to be aware of on these CTC-5s is that fixed bias HV regulation wasn't a great idea...On both of my CTC-5s I added a HV regulation control pot. It's pretty straightforward if you compare the CTC-7 and CTC-5 HV reg circuit schematics. The CTC-7 deletes one resistor and replaces it with a pot and a fixed resistor IIRC. The ability to adjust HV regulation helps with HV level in these sets.
