I bought some "germanium" diodes from ali express, but I didn't figure out how to test them. They showed unusually low dropout (in the order 0.2-0.35V, don't remember as it was long time ago). But are they really germanium and not some small-signal schottky? AFAIK curves are quite similar. Given the price (they were very cheap) and condition (absolutely new unsoldered), I think it just can't be 1n34. Imho it's schottky. If I find them I'll try to make some curves. |

In this application, stray capacitance and reverse recovery time are going to be more important than forward drop. I would have thought that the 1n914 would be ideal. Though, 1n4148 should do. Other point is that the LED driver, having no base resistor, is going to set a hard limit on the rectified voltage equal to its Vbe drop. This will load the oscillator heavily. Not sure if that is intended, but I would have thought not. |

The 1N270 is available new and should do just fine, also RF Shottky diodes, for example from the BAT15 series should be OK too. Cheers Alex |
