What is this transformer?
Does anyone know what this transformer is for? It has 4 pins; one primary, one secondary. The turns ratio is 1:3. At first I thought it was an interstage coupling transformer, but it has no air gap!

Re: What is this transformer?
Hi David, I would still say it is interstage coupling. The lams look as if they are a high flux material such as Radiometal. There may be an inherent airgap in the lams by means of their construction as they do not look like conventional E/I or T/U types.
It could even be a parallel fed type which normally has a cap in series with the pri winding to block DC. Ed |

Re: What is this transformer?
That transformer resembles a repeating coil used in telephone work.
Some come with a magnetic shield inside the case. REP is the American designator for a transformer that joins two telephone loops together, without DC coupling. They have various ratios.
