And the search begins... Thanks!

Thanks Patrick. It looks like you could use either a single pole or a double pole switch. In the U.S. double poles are usually used for high voltage devices (240V) as it's a safer way to disconnect from the mains when you bring in two 120V lines to an appliance.

Thanks for all the information.

Any time. For clarity, you were originally asking whether to fuse both line and neutral. That doesn't mean you can't use a single pole switch at all. I just wanted to be sure we're talking about the same thing. Also, in "Schurter speak" don't confuse fuse holder (part of the PEM "body") with the fuse drawer (the part that holds the fuses and slides out). I've seen that cause people to want to throw things... Also for some models, the drawer is an option / separate purchase. 😉

Some Options -

Single pole switch - Single Pole Fuse Holder
Double pole switch - Single Pole Fuse Holder
Double pole switch - Double Pole Fuse Holder - Single Fuse with Optional fuse drawer with neutral bridge
Double pole switch - Double Pole Fuse Holder - Dual Fuses

Cheers,
Patrick

and, most important thing - are you happy how it sings?

 

[timkrone]

I had a little hum at first, but a rework of the output wiring took care of it. I'm very, very pleased.

 

[Zen Mod]

Fugly!

It's been a year since I built my balanced version, and during that time only the single-ended were used. Yesterday I hooked the Iron Pre up to my balanced Mark Levinson and it sounded fantastic, and quiet, even though it was placed literally 4" behind the amp which has two enormous toroid transformers. I could detect no induced hum at all, even when I lifted the Iron Pre directly over the ML.

I built another for a friend last year, and he only wanted the single-ended jacks connected, but I think it's really a handy feature to connect at least one position for balanced use.

every preamp is good, but those with Iron are sacred

Did you enjoy "releasing" your preamp on us?

Thanks for all the help and inspiration.

Looking good, what does the knob do on the front panel?

I don't need you "us" to be in permanent state of joy

Hi all,
Could someone recommend a front panel switch that fits the balanced custom iron pre chassis from Gianluca?
Thanks!

@timkrone, your build looks great! Any issues with the Muse setup? I'm starting a very similar build in the near future.. Is that volume knob from AliExpress? I have a very similar one from there for my DCG3.. Was wondering if it will fit the stem on Franks kit. Great work!

 

[GKTAUDIO]

The AliExpress knobs tend to be metric. I used a nice set on my balanced Iron Pre but had to drill them out to fit the SAE pot shafts.

 

[SkyPirate]

Thanks @GKTAUDIO! Appreciate that!

 

[timkrone]

@SkyPirate No issues at all with Frank's MUSES setup on a balanced setup or Academy Audio on a single-ended version. Both are great. I honestly can't remember where I got those knobs.

Have fun!
