After several dissemble assemble cycles the oven heater started working, it is very slow reaching a stable frequency, about 12 hours. So maybe only one of the two transistors is working but this allows me to move on for now.
The frequency was closer but I changed a 33 PF capacitor to about 20 Pf across the crystal to get to the 5+ Mhz. My hope is I can restore the original cap when the heater is repaired. My FTS 4040 is now ramping the frequency but not locking, I have hope as it starts with a wide range and closes in on the correct frequency +- a few counts so maybe the tube is very weak and not dead. Will wait and hope it repairs itself:-) Stanley _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
