Re: Telefunken M204 TS E2 Commenced
While previously doing the investigation work leading up to Post 14, I replaced the 100uF C124 on the left channel that had previously appeared to have given problems when moved. So I rechecked that area and found the connection between C124 and R151 was open circuit.
By measuring, it was down to 1 piece of artwork track and I thought it was the solder pad at C124 so I scrapped back the lacquer to resolder the C124 pad to further along the track. But with lacquer removed I could see a tiny break across the track about 5mm from C124 pad.
After repairing the track break, the left channel is working fine again and strangely now the right channel VU is also working. Did not notice it at the time but looking at the photo (near middle) there may be a crack fault line either side of the track break (at 315 degrees) and a definite crack nearer the bottom of the photo.
Even though the right channel is working, comparing it to the left channel, the signal level is a lot lower, can compensate for this by winding the right channel record level up but this results in the signal clipping.
So there maybe a problem with the right channel signal gain.
But before I get too bogged down investigating it, I will reconnect the speakers to see if any Playback sound and if so check out recording.
