Output transformers for Line-level signal.
Hi to all
As this is my first post here you may asume that I just found out what a soldering iron is but actually I have been using it for years, but today I really found out what I can do with it.
As I am starting to actually understand some components and which way I shoud use a resiston in my schematics, found out that output transformer is very interesting thing...
So now I am building a tube pre amp for my studio. I have already finished scetching and the filtering section, some interesting controls and output stage with E88CC (first part is not that important).
So I have my E88CC as a final stage and I would like to end with something like output transformer.
I designed it up to match with Lundahl LL5402 or EDCOR XS 1100 but sadly I didn't manage to get them.
Instead I desided to buy OEP A262A2E
But then I found out that I know nothing about using one.
And now I am here asking.
1) If transformer is marked as 1+1:2+2 does it mean I could do stereo with it?
2) If transformer is marked 2:1 can I use it as 1:2 by just swaping primary and sec.?
And the most important question. Can I use OEP A262A2E instead of LL5402? (lets skip the quality and frequency response factor)
A2) No. As there are losses, the 1:2 will give you a 1:1.9 or something like that
A to the last Q: Show us the data sheets. E
OEP sheets and information.
A262A2E - OEP - datasheet
I hope it is enough information.
The A262A2E does not have the drive capability of the LL5402.
Not knowing your circuit and full purpose of it it is impossible to advise you.
The output stage is very similar to Redd 47. It also has ECC88 in the final stage.
Basically I am building a tube pre amp. with Ecc88 as an output stage that is inspired by Redd 47. It is working on line level, so line in and line out.
Find and read everything from Jensen and Rane and Jung and Self and etc, on balanced impedance connections.
Do not swap input and output transformers.
Do not invert transformers.
