Re: Frame cramp Baird M676 help
Hi Boater Sam. Pin 2 is the the triode section grid and the voltage is at -21v against a quote voltage of -40v . the anode is pin 1 which is at 99v against a quoted voltage of 115v. The 820k is good and has been replaced and the boost voltage is at around 800v which looks about right.
All caps are brand new or new old stock and tested at greater than 100 meg leakage at 250v before fitting.
Hi Argus25.
Thanks for some ideas to explore. I hadn't considered the ht rail folding during the sweep period. Something to look at. Also interesting idea to substitute a seperate ramp wave form from another source. I will also double check the resistance network in the vertical form and height network as they haven't all been checked. Will report back soon
