Great listening tests will be on Saturday 4.6.2011

 

[PMA]

How about set-up of the amplifier that will be tested on Saturday?

 

[Federmann]

I believe that you will attend.

PMA:
You will be able to communicate their impressions. Your English is much better than mine.

 

[Sendy]

Aw, nuts ! Your English is better than your amplifiers.

That was a low punch. 😕

 

[Sendy]

No, that was a warning.
Big differences between proclamations and reality.

They speak only empty words.

Sorry, it looks like 12Vpp. 6div x 2V.

 

[Federmann]

Probe 1:10

 

[Federmann]

Probe 1:1 Minimum sensitivity of the oscilloscope 5V/div

 

[PMA]

Really? I thought the transformer was 2 x 36V. I can't imagine getting 120Vpp from such PSU.

 

[Federmann]

Was measured another module. Supply voltage ± 66V.

Transformer 2 x 36V. Will be measured tomorrow.

 

[PMA]

Thank you for the explanation. I thought these images were related to your amp that was under test on Saturday, 4th June.

 

[Federmann]

Have a nice night.
