Finally we are introducing SILK hand wound Interstage coupling Transformer with several impedances and connections to suite your application.

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 compare 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
6. Custom design available

We select the best material and wind them with most sophisticate ways with precision to generate best signal transfer and reserve sonic purity to the highest level. Our SILK Interstage transformer is potted in beautiful cover with shield for minimum noise. The connections are made via terminal lugs underneath.
