concerning the "smaller" diodes:
The developer himself is using diodes of that type and I was told that
there are only 0,0001A flowing through it.
That part of the circuit is a protection circuit and not part of the
"real" power supply (see the explanation on the website for that,
I do not know enough to explain it to you)
concerning blown components:
- T07b - not T08b is broken
- D56 seems to be broken indeed
- caps are showing correct values,
but I can only measure 3nF across C54 - but I also get only 3nF across C53.
which should be 100nF (But I also only get those 3nF across the other caps of
that type (in the power supply for example) - Might be because my DMM is
not very accourate.
S/C also C55 and RD R11B as well as To8A If not check voltage feed in.
I did not understand that completely (maybe because I'm no native Englisch-speaker).
1. "S/C" short and capacity?
3. R11b is ok
4. other transistors (apart from T07b) are all ok
5. "If not check voltage feed in."
I don't understand that sentence
Here's the picture I promised:
There is another thing I did not mention yet:
While dismounting the board and the transistors from the heatsink
I recognized that the isloation pad on T07b was a little too short and
a small part of the bare metal was open to the heatsink.
(Should not have had contact, though)
May that have caused the problem?
Here's also a picture of the entire amps interior:
The damaged board is the one on the right.
