FREQUENCY RESPONSE measured using 600 ohm source and
15k ohm load
|
 |
| APPLICATION Exceptionally
high level, high bandwidth, low distortion 600 ohm or 200 ohm input transformer.
Suitable as replacement for original transformer in Trident A range, B
range, Fleximix and other vintage recording
studio units. No uncancelled
dc permitted in primary or secondary windings. |
| FEATURES
Unusually 70% Mumetal/30% M6 laminated core for minimal distortion even at
very high levels. Very high inductance ensures an input impedance of at least 1000 Ohms over a wide frequency rqange when the secondary is loaded with 50K Ohms. Heavy Mumetal screening can to ensure
immunity from hum fields. |
