Thank you.

The sound is very close to the original 176

Here you can listen to audio samples of the two Compressor - 176 and 175B to the master mix.

1.mp3 - without compressors

2.mp3 - processing compressors

Thanks JBB
can you send me a link without translation?
I can't listen the mp3...
Thanks

THANKS JBB!!!
2 info:
on layout : Un - Ch- Ua  where are connected?

I've one UTC A10 can work as input?
There is an alternative to Sowter as interstage?
THANKS!!!

Un  - filament voltage (5v)
Ua  - anode voltage (325v)
Ch  - shoke

UTC A10 this is what need.

There are many alternatives to the interstage transformers.

Hammond, Cinemag, Lundahl - it is also possible to use.

Specify the exact analogues transformers cannot.  Have not studied the issue in this direction.

Thanks!!!
5v? = 6.3v?
Thanks

For gz34 rectifier need use 5v: http://www.drtube.com/datasheets/gz34s-jj2003.pdf

Hi JBB
I've also an UTC 0-1
could be this a good input transformer?
Thanks

Hi

Transformer UTC O-1 can also be used.

Here to discuss the same issue: http://groupdiy.com/index.php?topic=17654.0

Nightmare, ( semi-joking )

now I'm gonna have to build this too. ( serious )

Thanks JBB, you are a very kind man to share this info so elegantly  ( actually )

regards

Michael

Thanks,

Good Luck in the build.

Hi
I'm building the 176!!!
I want to implement like Retro 176 the asymmetrical function and interstage trafo bypass,
Can someone help me?
THANKS!!!

Hi,

My congratulations!

Photos will be?

Hi JBB
I'm starting and I'm waiting the output transformer from sowter...
When the project is on the way I will post some images.
Asymmetry switches?
Interstage Bypass?
HP Filter?
THANKS!!!

JBB, very nice work!  I love seeing it.

I don't understand the questions.
