Default SG-230 problem

Cecil,

I had a look at the 1N4148, they are 2-pin.

The diodes in mine are Surface mount 3-pin.

Are the 1N4148 diodes for the old version board, before year 2000?

My board is the newer version, after year 2000

It looks like some of the SM 3-pin diodes D10, D9, etc have failed. I was
only testing with a 100 watts although it was with a very high SWR at the
time

Do I have to go to SGC for the diodes or is there a replacement that I
can use instead?


My SGC-230 manual says those are 1N4148 high speed
switching diodes which are one of the most popular
diodes of all time. They should be readily available
almost anywhere.
