Don't you find that in SM ?
Thanks. SM doesn’t show the brand and model number of the part. Just says 5v 1A 500ohm.
I opened the cover and checked. The part is Hamlin HE3321A0400 Reed Relay 5V 1A 500ohm
The symptom of the problem:
1. Sometimes left channel of CD Balance input low voice compared to right channel. The difference is in certain rate.
2. When I switched to use RCA of CD, no problem
3. Use other balance input (DVD, CD-R...) No problem
4. Use MM/MC input no problem.
5. Switch back to use CD balance input, problem happen.
6. When I press “Mono”, the sound from both channels are balance.
So I guess one of relays (total two relays for pin 2 and pin 3) of Balance input of CD has problem.
I don’t understand why such standard part failed too early. The age of my C2300 is approx 7 years old.
