T-L20 DI Box Transformer
The T-L20 is a high inductance 11:1 transformer designed for direct box use. It is unlike any other direct box transformer due to its toroidal design and high inductance. At a nominal primary inductance of 2300H it is capable of transmitting a clear and unaltered low end 50Hz and below even on high impedance sources.
The T-L20 is a great choice for custom Wolf Box style builds and other DIY direct box projects. If you have questions about the specs or performance of the T-L20 feel free to reach out through the contact page.
Custom One Off Winds
Ordering a single custom transformer from Alder is simple and fast. We offer custom toroidal transformers with a primary inductance from 20 - 2000 Henry and a secondary inductance of 1 - 20 Henry. To order you just select the desired values from two drop down menus on the product page.
You will receive an email confirming the resulting ratio to make sure we are on the same page before the order is fulfilled. The desired ratio will be exact, but inductance will fluctuate up to 20% due to core magnetic variation. Lead time is approximately two weeks. If you have questions about more technical details involved in custom transformers, feel free to reach out through the contact page.
