I have the K&K Audio Lundahl step-up and am using it with the Hagerman Trumpet. I have the 14db configuration (1:5 ratio), but Kevin supplies the schematic and if you can solder it will be easy to change to a 20db or 26db configuration. With the 14db setting total gain for my Benz L2 low output cartridge is 58db. Since I have a high gain amp and adjustable gain on my preamp this is enough for me. The other nice thing about the K&K step-up is you can easily plug in different resistor values to change the cartridge load. The Trumpet, like the Bugle is set at 47k ohm. I use a set of 47k ohm resistors in the step-up and the net is 940 ohms which works nicely with the L2 (there is a spreadsheet on the Galiber Design website that shows you the various calculations based on resistir values).
The K&K comes as a kit or Kevin can assemble it for you. You could also just buy the transformers and build your own. In all, this has been a great addition to my Trumpet and after about a 100 hours of break in (you can connect the output of the step-up to the output on your CDP to break it in faster) the step-up was good to go.
