Champo,
I'm afraid I cannot offer any other "hints or kinks" in regards to this issue.
I have the same schematic you posted and it is vastly different from Sam's CB-5.

I have been following along with the Sam's manual-where according to Sam's;
Valve V12 is the final amplifier tube and is a tube type 12BH7A.
Valve V2 is the receive/transmit oscillator and is a tube type 6AN8

According to the factory print you and I have;
Valve V6 is the final amplifier tube and is a tube type 12BH7A.
Valve V12 is the receive/transmit oscillator tube and is a tube type 6AN8.

There are many inconsistencies between the 2 schematics. Makes me think if the "Factory" schematic is true to your example, the Sam's manual Alignment Instructions cannot be trusted.

My Regency Range Gain is in the "To Do" pile and I have no plans to start on it in the near future. Previous thoughts have been to gut the chassis and install a modern (no tube) chassis in the case just for something different. So it is in the "To Do" pile when time allows.
