I am currently developing a new SUT (Step up Transformer) for the audio market which will come in several standard versions:
1:10, 1:15 or 16 and 1:20 step up (20, 24 and 26dB gain) with others to custom order.
The standard loading for these will be 100 Ohms but each unit can be specified for a particular cartridge loading.
Capacitance loading may also be offered as an option for those wanting a damped HF response (helps to reduce sensitivity to resistive loading too which means a better cart/SUT match).
These will be supplied in custom built casings using high quality connections and will ONLY be available from RFC and a select group of dealerships.
Expect cost to be in the region of £300 to £400 which will be market leading for such high quality SUTs.
The transformers will be all hand wound by an industry expert and will all be custom designed and built to my own specification.
The specs for the 1:10 SUT which will shortly be offered on trial to AoS members is as follows:
FR (within 0.1dB): 20Hz to 20KHz;
FR: (within 1dB): 10 Hz to 38KHz
Resistive (reflected load): 100 Ohms
This will be passed around AoS members interested in reviewing or trying the SUT. Just leave me (on THIS thread) details of your MC cartridge and I can confirm whether the prototype would be a suitable match.
There will also be Special Edition RFC SUTs made in strictly limited numbers which will have a one-off finish and will use the very highest quality connectors and wiring. Price tbc but expect them to be very competitive compared with the competition.
