Incoming B-6...Might be a basket case...will need Avionics help for sure !!! FIXED, again !!!

I found a short thread postet 2009 to which Avionic responded, saying that the guy should switch the probes because this values were printed when analog multimeters were standard. So I will adjust to -2.5V and enjoy my B-6.

? Negative Idle current on Yamaha M-50 ?​

Was it you or Asmo looking for a new speaker relay? Schrank PT270024 fits, I use it in my B-6.

In all amplifiers I have adjusted it was the case that turning the trimpots clockwise increased the bias. In the B-6 it should be different? I am asking myself if the SM is wrong.

It might be, but in the other B-6 thread I think they were able to dial it in.

I have to revisit it at some point and do like the video showed, my amp doesn't get that hot when playing for an hour or so.

? Negative Idle current on Yamaha M-50 ?

I am seeking some assistance on making adjustments on my M-50. Following the service manual, to measure/adjust idle current, the (+) lead goes to "TPO" and (-) lead goes to "TPE ". With this connection I'm measuring about - 45mV on each channel. A negative value ?? Is there something...

Now I have to open up my B-6 for the third time!!!

And I too have those Mundorf caps , I have 4 I was going to use them in my B-1 but everyone here suggested they aren't the right physical size to handle the output of the B-1 .

Three times is nothing. If you are successful squeezing the Mundorf 15.000 uF caps in, please post the procedure.
Regarding the relay, the brand name is Schrack, of course. I got it from Farnell.
