Silk Interstage Transformers are best characterized by :
1.Wide bandwidth due to special winding arrangement for each particular design and impedance
2. Best low frequency response due to its high inductance compared to its competitors (2-3 times lower in THD at 20Hz is typical for SILK interstage)
3. Best high frequency response even when apply direct current up to 2.5 times its competitors allowing the use of low Zp tube with high current requirement
4. Very tight unit to unit, coil to coil tolerance in terms of response curve, inductance, DCR and square wave shape
5. Designed and Developed under real tube circuit to be used
Selected best material and precision wound for best signal transfer and sonic purity. Connections are made via terminal lugs underneath.
