I just finished a cap kit on a monitor that was not known whether it was working or not. Chassis had dirt and debris on it, didn't want to fire it up before capping and cleaning.

Cap kit is done, and no life from the assembly.

I have caps for C505 and C601 left over.

C505 is a ceramic cap. Should I replace that with the electrolytic?

C601, I don't find anywhere, and it is also not shown on this cap map at Ian Kellogg's site.

Is it okay to assume the replacement for C601 is not intended for the KGR-1901 (the cap kit also covers 1902 and 1903 series monitors)?
 
c505 is a polarized position with the polarity labeled on the pcb and YES replace it.

c601 i don't think is on the 1901.

this is from memory but i am pretty sure.
 
I saw the screen printing on the board at c505 indicates an electrolytic cap. Thanks for confirming.
 
Thanks, guys. I've got C505 and the 2 filter caps which weren't part of the cap kit, which I will swap in today or tomorrow. I see in the manual, R707 adjusts B+. Where is B+ measured.

Is there a troublshooting guide or flowchart for the Sampo's, like there is for the MC9000's and 20EZ's?

If still no power after the last few caps are swapped and b+ is adjusted, what are the next steps?
 
Sampo KGR1901, 1902 and 1903 B+ adjustment: Adjust B+ at R707 and set it to 110vdc. Read B+ as follows: red meter lead on R612 and black meter lead on chassis ground.
 
R707 doesn't really seem to do anything. I'm measuring B+ at around 31.2V at power up. It slowly climbs a bit more to around 36V. I turned R707 and it climbed to 38V. I then turned it back down to about the its center point, and it stayed at 38V.

Thoughts?
