Hello, I purchased these transformers on ebay quite a while ago and finally pulled them out for a possible small tube amp build. Unfortunately, there was no real information about them. The ebay post had the following information:
2 vintage Output Transformers for SE/PP Tube Amps EL84 ECL82
Type Philips Mullard
here is a pair of vintage telefunken transformers for tube projects.
The transformers are made for SE/PP Amps for EL84 tubes or ECL82 Tubes
The Transformer have tree coils , one with middle tab
I checked the coils with a multimeter :
Coil 1,pin6 / 7) ca 262 Ohm
Coil 2 (Middle tab at 60 Ohm) : 557 ohm
Coil3 (Speaker output) ca 1 Ohm (for 4 Ohm Impedance speaker)
The transformers are in good used condition, it was original used by telefunken for a EL84 PP system and also for ECL82 SE systems with a 4 Ohm Speaker
A original circuit diagram can be included if needed
Measurements of the transformer Body 50x40x20 mm
Not really understanding the part about being good for SE or PP. Was hoping someone might have an idea about these things. Here are some pics:
