Thanks in advance!
Pin #4 of 6F5 is plate. Pin #5 of 6F6 is grid #1. The unit you found may be a combination of 2 capacitors shown in the schematic? You don't want anything between these pins except capacitors.

:I found a strange component between the pin 4 in 6F5 and pin 5 on the 6F6. I thought of a capacitor in form but not a condenser. I opened it by removing the paper and a black paste crystallized and then I found a strange piece of metal that appears as a thermal switch that I measured with the tester and has no continuity between the ends. I do not know which component it is but I do not think it is a capacitor or a resistor ... anyone know what I mean? I can send a picture to someone kindly tell me that it is and what does this component?
:Thanks in advance!

Ok ... ! I do not want anything between these pins except capacitors as you say, but the component that I mentioned is there ... I can send you a picture? ... you telling me some email so I can forward it to you to observe it please?
Excuse my English. I live in the Canary Islands, Spain and I am very grateful to you for your reply.
Believe what you found is a dual capacitor used for tone control?
You can get my email address by clicking on my name, above.
Your English is very good. Much better than my Spanish...

. . . that olde RCA has NOW introduced you to GENERATION 1 mica capacitors ! end tabs inserted within the metal housing and then the slipping in of the mica sheets. to initially test the units capacitance, it is reading 163 mmfd so she tightens down on the clamp that compresses the outer housing shell. Supplied are the RCA sets chassis photo, the pictorial layout of the set and finally a cut out of that portion of the schematic circuitry being involved. C7 - - - C11 - - - C15 - - - C21 - - - C33 - - - C-46 and C48 positions. when switched to the highest SW band the two caps are in series and effectively act as a .001 ufd cap. of hearing weaker AM stations . . . . as well as code.

Pay no attention to Edd unless it is about radios. He is probably an escapee from an asylum, but he surely knows radios. We are not all like Edd. We are more sane and less smart.

Very grateful for your extensive explanation and the time expended on it. I have clarified many things I don't know. Nice work Edd ... I'm just an amateur that has a lot to learn from people like you. God bless you!
Best regards !
