Default This one, followed the one i used as reference to modifications

And this one seems more modern...made 34 years ago, as the other was made 35 years ago.

Very old both of them.

This one rated to 140 RMS per channel, both channels working...and 175W when only one channel was operating.

I think this one can be better than the one i made using modifications.

What do you think, only seeing, can this produce a better sound than the Münster?

I am asking because do not know, and beeing in doubts, trying to have some inputs.

thank you in advance the attention

regards,

Carlos

No, the globalfeedback is standard voltagefeedback.
The "accidental currentfeedback" is hidden. It's the 330ohm
in negative rail between diffamp and vas.
I am not sure what it does, but it's more like some bootstrapped
extra vas inside diffamp.
It's no real feedback because of the electrolytic.

Default Finally, with the bless of God!!!, one man explained that "thing" to us, and....

Really wanting us to understand what he means.

Now, it is more clear to me what i had perceived many times, some people, with native english language do not talk clear...they do not know how to be clear, or do not want us to understand.

Maybe too much obvious for them to explain us.

My Dear Mike..... i will send one Rostbrattwurst from München to you, with some good beer.... we will eat and drink together and i will say Danke shöen mein lieben freund (thank you my beloved friend).

Finally....Glory to the Skies..... at least one!!!

regards,

Carlos
