When I replaced the rectifier on my CTC-11 board, I got two opinions.

One guy said he used "ordinary power supply diodes," which I took to mean 1N4007.

Another said those are too slow and sent me some "fast slew" diodes (his term) which I installed. Hard to read the type number when they are installed, but it may be 1937. At least, the last three digits are 937.

If you have a bunch of 1N4007 lying around, you could try those and see what happens. Pretty cheap experiment as long as you don't fry the board.
