Hi Tobias
A bunch of nice 4-gang pots coming in, send You one next week. |

Very good work.
I like the pcbs a lot. |

Tobias,
very nice looking project! One question for you: where did you buy your components? ie. resistors, capactiors and so on?

| promitheus |
| what potis are you going to used for balanced output? |

Hello Kari!
Everything is from ELFA, except PCB, Trafos & Rectifier-diodes
I did buy some 1N4005, but I had some OnSemi MSR860 laying around so I used them instead.
ELFA is pretty expensive but I bought it there anyway :xeye:
I have all the ordering numbers if you want them, but it isn't so hard to find.

Hello promitheus!
I really wish I knew :(
Btw, nice things you got going there!

Tobias, the cheap attenuators you linked to are now receiving a lot of complaints because they are noisy. Loud clicks between positions.
The new thread linked to by UrSv looks like a good thing- but as you will see from my last post there, we BoSoZ people need to stick together and order what we need- it's tough with the balanced output.... |
|

| UrSv |
| And Elma makes custom configurations and the prices are not bad. |

I need comments about putting the pot between the 2 outputs.
If so, we can use the same switch Brian is getting, just different resisitors What do you guys think? |
|
|
| UrSv |
| I think that works fine until you run unbalanced out. I'm sure I saw something somewhere ín a thread that Pass:ed as initiated. |
|
|
| Variac |
That's a good point. I may need to run unbalanced out at some point. Using 4 decks, we could make a balanced shunt attenuator.
What do you think of that? An 8 deck attenuator switch is going to be tooo expensive I think- if it's available at all.
I also already have some 6 deck switches which I am planning to use. In this case I would just use 4 of the decks. Mainly I just want a BOSOZ group resistor buy- then people get their switches from Brian. |

| Two 4 deck attenuators - one for input and one for output. |
|

| UrSv |
One could always contemplate on not using the input ones as most likely (maybe?) most sources will run about the same output level and thus the input divider , if needed, could be tuned to that for the optimum input level. Using 4 deck shunt is simple enough and would be easier to get than 8 deck. I would probably also prefer shunt output attenuation.
Also, Elma does make custom orders and the prices direct from factory are not too bad IMHO. An 8-deck was be perfectly possible and comes with an additional supporting bracket. |

| Tricky thing this :bawling: |

Another question:
Is this a correct/suitable position for the NTC?
My PSU board
Thanks |

A 4Decker in construction....
I have dismounted two Electroswitch 2 decks to make a 4 decker...
and build a 10 K ladder type
Best regards.
PS: Thanks to Nelson for providing the material.
Alain. |

How many are interested in an 8 pole switch?
Im asking cause im already working on a stackable switch, and if enough people would be interested in such, it could be made for a reasonable price.
