CUSTOM DESIGN

FREE SERVICE
This is available for valve output transformers,  mains transformers,  power chokes and most pro-audio transformers and EQ inductors. The performance is guaranteed to meet your specification after acceptance.

You can choose the package style and several other options as well as the basic design. See POWER PACKAGES. The prices of most custom power transformers and chokes depend on the standard size we use. If you can calculate the power rating you may be able to estimate the size code. See PRICE/SIZE INFO. For help to calculate HT voltages and currents for various filter and rectifier circuits see How to Specify HT Windings

Please complete and submit your specification(s)

PREMIUM SERVICE
This new service is available for cases where we cannot fully predict the performance or we cannot use our computer based design tools or the customer is uncertain of the requirements.  We will do a design based partly on simulation and partly by judgement. We will try to get as close as possible to your target parameters. We charge a fee of 50 UKPounds in addition to the first sample cost. This charge will cover design costs for a further two design iterations which you may request after your evaluation. You only pay the list price for further samples.

Please complete and submit your specification:

PREMIUM CUSTOM DESIGN REQUEST

To obtain a quotation or place an order for a custom design you first need to submit  your specification. Please give each specification a reference e.g. "T1".  When we have received your specification we will tell you the size code And give you a new reference with a date code (e.g.: JS-T1-230600)  You will be able to order or quote by size code, options, and your spec new reference.  If you can estimate the size you can obtain a tentative quote immediately using your own reference code.

If you need some help or just want to discuss an idea please feel free to contact technical support.
