VINTAGE RECORDING STUDIO PRODUCTS |
|---|
 |
A NEW SERVICE for recreation or replacement or
repair of vintage studio compressors, microphone amplifiers, equalizers,
bridging and distribution amplifiers etc using tubes or transistors. There
may be small differences in dimensions, taps and in the detailed
specification but we are confident these transformers will have the
"original sound"
CUSTOM DESIGN SERVICE We are extending our custom design service to include this type of transformer. We will not make a charge for the design provided we accept the requirement as being of general interest. We can work from circuits, actual transformers loaned to us or from specifications. We may offer the service on a "best efforts" basis if we cannot be sure of meeting a particular performance. EQ INDUCTORS Please see separate page GENERIC PRODUCTS Many manufacturers used generic transformers which you may find on our Pre-Amp and Line Amp page or our Pro-Audio page. Please feel free to contact technical support for assistance. PRICE and SHIPPING cost can be found by clicking on the type number or using SEARCH an using the type number as the search word |
