Title: Bought sex SEX 3.0 + C4S - Crackling on both channels and high voltage check
Post by: eudisld15 on August 11, 2020, 04:14:29 PM

I recently bought this SEX used. During shipping the wooden chassis arrived damaged and collapsed.

I double checked everything, glued the chassis back when testing I hear some crackling on both channels. Crackling got worse as volume was turned up. I could hear audio just fine.

It passed the resistance check but failed voltage check.

2 - 150
3 - 39
4 - 0
5 - 0
6 - 772
7 - 839
10 - 787
16 - 140
18 - 0
19 - 0
20 - 772
21 - 838
24 - 789

h2 - 6
h4 - 0 (108.4ohm)
h5 - 6
h7 - 0 (108.3ohm)

0A - 150.6
0B - 140.4


Anyone has any ideas what could have gone wrong?

If those are voltages, I would guess that it was wired for 120v power input, and plugged into a 230v power outlet. If that is the case. I'm sorry to say that many components may have been damaged. Can you post a photograph of the power transformer wiring?

Okay one moment.

However it is plugged into a 120v outlet.

Huh. Well then something else is wrong. Pictures of the wiring, and you should check your meter - is it set to read DC or AC? Is the battery good?
