Cyrus II r/ch distorcion
I´m new to this forum and I´ve been digging here trying to find a solution to a problem i´ll try to discribe the best I can.
I´m the proud owner of a Cyrus II issue 07 date 9111 bougth secondhand 15 years ago and apart a problem some years ago allays have worked perfectely.
Some time ago I noticed the sound on rigth channel was "closed", no bass, no treble, only arround the middles and sound level lower then the left channel. Have been trying to find a solution but without success. Already cleanned knobs.
Any kind of help is welcome, I´m not an expert on electronics but I have some experience.
UPDATE: After more readings in this forum regarding similar problems,a user (godfrey) mencioned about a speaker problem and I went to check that and, indeed, it is a speaker problem, the speakers are a TDL RTL3, I disassemble the entry part and made a bypass between input A and input B and now it sounds alot better.
Anyway, once Amp is open, what are the mods I can do to improve it´s performance a bit more? Capacitors on PSX? capacitors on Amp?
(ps. sorry my english)
Have you checked the old gold type caps in the preamp stage as these can dry or leak..
Next trace the audio signal around the preamp stage to ensure clean signal, these amps use Darlington o/ps with a catch diode built in test all out puts..
See how you get on.
Regarding those "gold type caps" I dont see any "gold" components except the ones close to the diodes (rectifiers) on power IN
Are you talking about 2 caps below green ribbon c43 and c44 (470/6) ?
