Default Re: Microvitec Cub 1431 Power but no picture.

I thought it was unlikely that the tube was dead, thanks for the information about the EHT. I feel a little safer knowing it is not just "Out in the open".

I've worked on a lot of amplifiers and some valve amps. My multi meters go up to 600 or 1000VDC. The highest voltage on a valve amp I've worked on would be in the region of 400V.

I appreciate this is high voltage and I do want to proceed cautiously if it isn't an overly complex fault.

Thanks for the manual - I had already looked at that one but this doesn't match the schematics and looks to be a Series 4 and not a Series 3. There is only one fuse present and the layout is completely different.
