The MC1 Moving Coil Lundahl Step Up Transformer Preamp provides you with a moving coil SUT unit, built, tested and matched to your cartridge offering a range of Lundahl transformers and loading options to meet any need.
Features
Premium Lundahl transformers
High quality RCA connectors
Gold plated PCB
Selectable ground lift
Selectable step up gain
Configurable loading
High frequency load
Built and tested
Standard Transformer
The standard transformer option use either the cutoms made LL1678XL for 1:16 & 1:32 step up ratios, or the LL9226XL for 1:10 & 1:20 step up ratios. Don't be fooled by the term "standard", these are still exceptional moving coil step up transformers.
Nickel Core Transformer
The Nickel Core option uses either the LL1963, LL1933 or LL1943 Lundahl transformer, depending on your gain requirements. It is available in 1:3 & 1:6 step up ratios (LL1963), 1:8 & 1:16 step up ratios (LL1933) or 1:16 & 1:32 step up ratios (LL1943).
The Nickel core transformers are a premium moving coil step up transformer and are a lower distortion alternative to the amorphous cores.
Amorphous Core Transformer
The Amorphous Core option uses either the LL1961, LL1931, LL1971, or LL1941 Lundahl transformer, depending on your gain requirements. It is available in 1:3 & 1:6 step up ratios (LL1961), 1:8 & 1:16 step up ratios (LL1931), 1:12 & 1:24 step up ratios (LL1971) or 1:16 & 1:32 step up ratios (LL1941).
The amorphous core transformers are probably the best moving coil step up transformers available on the market.
Loading
2 x 6 way DIP switches allow you to choose from a cariety of secondary loading options, including an empty resistor footprint in case you want to use your own value. There are 2 further options for primary loading for cartridges that require very low impedance loads, without compromising bandwidth.
High Frequency Load
A bypassable high frequency load is offered for low impednace cartridges, this damps down high frequency ringing and can be selected at the users disrection.
Gain
2 gains options are provided for each unit, selectable by switches.
Delivery
We usually have stock of all variants of the MC1, however sometimes there may be a 4-8 week lead time on transformers from the factory. If in doubt send us an email.
