Salas,

I did my conversion to the folded and the results are outstanding! Lower noise floor and better sence of timing. Very recommended 🙂

My MC is .47 output.

Thanks,

 

[Salas]

You used to have the MM with SUT? Now you converted to full MC folded? K369 or 170s?

Where in this thread can I find the schematic for the "folded RIAA"? 😕

Thanks,

I always thought the words were "from a land down under where women glow and men chunder"!! 😀

You'll have to Google "chunder". 😀 (Also known as "the technicolour yawn". 😀 )

I know chunder, what is zombie btw? Some word for strong pot? They start in a fried out combie with hilarious hair and weary in the classic video.

While we are in OT mode, how is Athens covered by snow? 🙂

 

[Salas]

In the centre it lasted little, but was nice.

Yes, I dropped the transformers earlier and increased gain. I used two 170's with 4.9ohm on each source. I did have to adjust R3 a little to hit the range for VR1.

Aha - it is "Kombie", not zombie, Salas. A "Kombie" was - still is - one of those VW vans which you could convert into a car to go camping in. And "fried out" means stuffed - ie. mechanically on its last legs. 🙂

Nice. Completely new board, or you just did a rework?

 

[Botte]

Just a rework with the same EQ parts, I did add the extra 170 to the output.

Many thanks, 🙂
