Need help with a 2076 diode replacement -

I am reparing a Nikko 1415 with a fried left channel amp.

I am trying to find a diode replacement for a 2076 . The service manual calls for a 1S2076 Si-DJ diode as a various detector.

VRM - Peak 70v
reverse voltage 60v
peak forward IFM 450mA
avarage rectified 150mA
forward voltage typical 0.v

this diode is in the left channel main . there are 2

Thank You

My 2 years of audio repair , very obvious. I only work on my own stuff that my good friend and 30 year tech wont touch and tells me to throw away.

I will keep on learning though. It looks like a misprint in the Nikko 1415 service manual .

Or a misread. Thank You
 
Crossed to a ECG 519 in one of my old books, your specs look close, except peak reverse voltage is 100 instead of 70 but that could be the sub has a higher rating and it is a fast switching type with recovery time of 4 ns, forward average 200ma, peak 450ma, close to what you listed. I don't guess the service manual you have list the oem supplier, ratings may vary from one supplier to another, but I bet the one Petehall347 listed would work.

Using your DVM on "diode check", measure the voltage drop on the good one in the other channel. If it's something between 0.5 and 0.8 volts, put in a 1N4148. If you don't have that, put in a 1N914. Heck, a 1N400x would probably work. The only place you usually need special diodes is detectors in tuners (often germanium) and double diodes used for thermal compensation (just use two). Obviously power circuits will need power diodes.

Electrically, the forward voltage may be off as much as 150mV at low currents, which probably won't matter, but a more practical issue is that the lead diameter of the larger 1N400x diodes will probably render them useless without enlarging the holes in the PC board. I try to avoid such things unless absolutely necessary.
