Does anyone have the correct rectifier diode values or replacement part numbers for a fisher kx200 int-amp available? There are four rectifier diodes in the power supply. The schematic gives fisher numbers of sr806-126 and sr851-122. Thank you in advance!

1N4007s have adequate ratings (1A, 1000 peak volts) for most any tube application. 1N5408 have a higher current rating, heavier leads. My favorite: MUR4100E - rated 4A/1000PIV, and is high speed for less switching noise. 60 cents each at Mouser.
