HOW TO TST RTC1 ? 

A simple continuity check can be done measuring the cold resistance between pins 2 and 3 - the two smaller pins - which could measure somewhere around 200 to 500 ohms. A more accurate test could be made applying 50 V rms between the same pins and measuring the current which should be around 300 mA AC. The test could aldo be done in DC.

HOW TO TST RTC1 ? 

Hello,

I have check my used RTC1 as in the circuit diagram of the Lemouzy TC54 radio

"Resistor" A  approx. 30 ohms cold is for approx. 110 V network with 5 tubes, eg 3 x 6.3V + 2 x 25V heating and 0,3 A heating current

V secteurI (A)V filamentV (RTC1)
800,2150            30  
900,2355            35  
1000,2560            40  
1100,2765            45  
1200,2970            50  
1300,3174            56  

"Resistor" B  approx. 19 ohms cold,

For 220V network the two resitor A + Bare serial switched with  5 tubes, eg 3 x 6.3V + 2 x 25V heating.

V secteurI (A)V filamentV (RTC1)
1000,1843            57  
1100,1947            63

2000,378         122  
2200,3276         144  
2400,3480         160  

Note : In the Lemouzy TC54 a 70 ohms are used with "Resistor" A for 130 V Network and or with A + B for 240V network.

Kind regards
