| APPLICATION High performance 20W single ended output transformer for use 300B, 2A3 or similar valve requiring a 2500 ohm reflected load. For those who prefer to operate the 300B with a 3500 ohm load and are looking for a very conservatively designed transformer for this valve type SA08 is recommended. | |||
| FEATURES Highest grade low loss (M6) grain oriented silicon iron core for minimal distortion. 14 interleaved winding sections to maximize bandwidth and ensure clean transient response. Low copper resistance to minimize losses and maximize loudspeaker damping. 4 separate secondary windings (See below) for optimum matching to load without the use of tapped windings which can reduce HF response. Optional secondary winding configuration. Optional shrouded or open frame package styles. | |||
