Ok, got in late from work last night and quickly checked the LO. I checked with my scope the top end of c35, well between c35 and c5. I checked on all voltage divisions and time divisions, nothing. Sorry if i do not quite understand this yet. How is it if i inject a tone at c1, a clear tone can be heard through the speaker if the L0 is not working? I guess i need to go back and check V1 voltages? If i remember from my previous tests correctly though, these were ok. I think all my heaters were running 1.3 volts.
Many thanks.
Dave.
