Hello,
Excuse me for writing in English but my German is very poor, i hope this is ok?
I live in Sweden and read this board mostly by the help of Google translate
I recently bought a Dual CR 1780, visually it looks very good unfortunately one channel on the amplifier board is burnt.
The components i know is broken (visually and measured) are these:
R325, R335 (cracked, burnt)
T312 (cracked, burnt)
T314 (short C <-> E)
T310 (short B <-> C <-> E)
So, what do you think? How much do i need to replace to get this machine running?
I really want it to work again, so i appreciate any comments and help on this matter.
I would also be thankful if anyone can suggest replacements for T310 & T314.
I have verified that the pre-amp is working ok by connecting it to another amp, no problem there.
(i am used to work with electronics, so i can measure and work (replace components, solder etc.) on the board pretty easily)
