Hi Ty, thank you for coming to my assistance. I worked most of the afternoon on the amp and was able to get everything working, reduced the B-from 197v to 148-50v by increasing R5 from 270 to 3K ohms. Started the amp this mourning and nothing was right, B+ 230V instead of the normal 277V, B- was 148V, but the left channel again could not read a value across R29. Waited a few hours and tried again, B+ was up to 277V everything else was the same. Came back after lunch and tried again, B+ now down to 230V again. It is time to trash this build, do not have the time nor the knowledge to progress further.
I do have another board that has all components except the tube sockets on the back side of the board, works perfectly, will preceed with this board.
Because I am using the Hammond 270FX with this board also, the B- is 197V. Is increasing R5 to 3K ohms the correct was to reduce the B-, or is increasing R6 or the Caps a better solution.
Ty, again thank you for your assistance.
Cordially,
Lee Hankins
