Also, you should show a photo of where it came from (and describe what the board is from). Such context is important to be sure the response is correct...
Also, it appears working does it not?

Probably a Zenner.
Could be.. I thought maybe the color code was brown-yellow-gray, 148, i.e. maybe 1N4148, but I've not seen that before.
Anyway, hopefully photo(s) can make it clearer, or some context.
Working, yes. But It does not reach the specification at all. Main caps and a few more small capacitors are now replaced. Only one, the 100uf capacitor was close to spec.
Are there not about 8 of them, all with the same color code? I can't tell from the photo too well, you'd have to look physically.
If there are, then you could temporarily swap a couple of them over (unlikely they are all fried) and see if it makes a difference If it does not, then that component is unlikely to be faulty.
Anyway, according to https://www.vintage-radio.net/forum/showthread.php?p=1595375 it might be a 1N4148 with one band missing or implied.
I I measured and 2 seem to be ok, one measures higher and the others don't work
Yes, there 8 light blue ones
I can not find one 1N4148 with 0.7v forward voltage
Yes, 1N4148.
