Now, the seller already told me the voltage rectifier was bust, so he removed the outgoing wire from the Big Blue cap as a precaution.
Robin had seen the Asteroids posted on my Facebook page and I felt he was interested to see it and also....it was time for a cup-of -coffee and a chat anyway so I asked him over to come have a look.
So we first had a look at those rectifiers. On LL and Asteroids Power bricks there are small PCBs with two big diodes which do a half-wave rectification.
Here the set-up was similar but....I was puzzled by what I was looking at. It turned out to be some totally weird diodes which I've never seen before. They were soldered on one side to the fuse holders (both fuses were blown, no wonder because both diodes were totally shorted and thus needed to be replaced).
The other side was kinda held together by a clamp, electrically connecting them and the wire that runs to the plus of the Big Blue.
There was a bit of confusion but I checked and showed the manual to Robin and it's easy enough to understand. We removed the diodes, tested them again (both full short) and so we had to think of replacing them somehow because we were both very curious to see if there would be some life in the machine
I thought I still had some pretty fat diodes around but couldn't find them, but then we got the ida that we could use "half" a diode bridge. I have a couple of those in my stack of shit..I mean parts boxes, so got one out, checked it and hooked it up temporarily....
We could simple solder the AC coming from both fuses to the AC in of the bridge rectifier, and the + to the outgoing wire to the Big Blue.
The minus output has nothing to do in this situation since we only need a half rectification (in fact, trying to hook up the minus to anything would result in disaster
Now anyone ever seen this type of diodes ? I have seen lots of kinds but this was new to me...
