I have a lovely Pendulum to cover my tube pre needs. I don't have a tube mic, however. The cheap ones I've auditioned have a bit of gauze over the picture, but I assume good ones can sound spectacular and clear. Here's question 1. All things being equal which I know they are not, will a nice tube pre obviate a tube mic.

I would like to record a speaker that has a 25v audio transformer attached to it local to the speaker. Removing the x-former is not possible, for they are paging speakers driven by a paging amp. Can I attach the secondary of another 25v transformer on the other end of the wire, thus the primary of the second transformer would then be a hi-Z input?

Any help is most appreciated, thanks

Hey everyone,

This is a post for all the techies out there:

Anybody ever hear of Malmac X10 AJ line transformers? They're 600 ohms:600 ohms and came out of an old Ampex duplicating chain recorder electronics, I think. Are they any good?

Thanks,

Seth

PS. This is all CJ's fault. I would have chucked them before.

I would like to build some API mic preamp copies.

I found (8) API 2623-4 output transformers.

Question: which api can I build with these ?

Question: is $200 for (8) a fair price ?

Thanks !

Hi

This is a subject that has been talked about already (maybe), but I'd like to know where I can find some knowledgeable infos (web sites, books...apart from this site :D ) about these two different design ethics, so that I'll be more conscious when I'd shop for a new preamp (or mic).

Thanx

L.G.

:) Hi Sebatron ! I edited the boring history of why I am asking this question, sorry.

Is it desirable to have an input transformer that provides a maximum output, or is there a balance judgment between response, gain, and other things?

Isolation transformers, has anyone tried using these things? Did it help? What type? THANX
