I'm not sure there is a catalog.  I have a few part numbers,  but haven't had much success in getting responses via email.

They seem to have division catalogs for -
    EMI Filters
    Motors & Blowers
    Photo Controls
    DC Contactors
Go to the bottom of the product division and you will find the catalog PDF links.

That site’s a work in progress. You can’t get at any audio product descriptions from the site navigation, but if you search “audio site:altrancorp.com” on Google, it brings up hidden links to the 3 or 4 audio products they’ve built pages for. Couple of inputs and a couple of outputs.

They do a lot of OEM work as we know here, but they don’t make it easy for individuals to buy from them. Shame. I have a couple of 4:1 tube outputs they built, and they’re nice transformers.

I remenber that a few of diyers used their mic transformer C3402 on  MA1 germanium pre.
They said me it sounded very nice. IMHO, I tested  it personally and I like it so I added the C3402 on MA1's components list as option. Its price was very fine too. 
Just to add my opinion.

did the search as described and found a few part numbers but all were 1:1 transformers

What do you need? Hairball stocks the 3837

I need a catalog with part numbers. looking for mic input stuff

 

[pucho812]

sent them an e-mail yesterday, lets see if they respond. I may just have to call them

C-3402-2 is a 1:4  mic input

If you do get a catalog it would be useful to everyone, they also make tapped inductors for EQs

 

[pucho812]

any info I get I will spread around

a catalogue would be very nice, prices list too.
The tapped inductors may be very interesting, just for an eq.

update I called altar....

automated messaging system, left a message.

I think that a group buy might be interesting if discount prices for quantity are good.
For the C-3402-2 may be an idea.

The C-3402-2 can be used with 1:8 configuration too.
The  C-3402-2 has two primaries. With these ones  in series the ratio is 1:4. If the primaries are in parallel it becomes 1:8.
The socket is CMMI-8PCA compatible, so it can be used on 312 clones.

Good info regarding the 3402. I would be in for a pair if a group buy happened.

Moreover Warm WA412 uses  Altran ones on input and out, but seems that these transformers on WA412 are custom products.

We had a groupbuy here for their API style transformers 8ish years ago.
I really like them...
My fav 312's have the Altrans on the input.

Altran C 3402-2 - api input
Altran 3865  - api output

I contacted them years ago to buy more but never heard back.
I'd grab a box full if available.
From memory, the inputs were $35 and the outs $15.
