EMIA Phono Specifications...

.
hello boys and girls... dave and I decided it is time to post some information about what is inside those petite minimalist boxes that have been showing up at HiFi events the last year or so.... the first batch is sold out and was very well received... that means it is time for the next batch.. which also means we need to tell you what is hiding underneath the hood...


 [the two boxes on the bottom are the phono stage - power supply and signal chassis]



basically, this is anything dave and I would build and endorse... heavy... tube rectified... choke input... single ended... direct coupled for high resolution... and what we feel is a very novel method of implementing the RIAA equalization... it removes the giant series resistor that is always a dynamics killer... and of course no feedback... the official blurb is:

The Emia phono is a tube based medium gain MM phono stage that uses a pentode input tube directly coupled to a triode output tube with shunt RIAA correction and zero feedback. This phono allows a wide range of tube types to be used without altering the RIAA characteristics. By simply rolling in these different tubes, the sonic signature of the preamplifier can be adjusted to taste. External plugs allow easy access to nearly infinite adjustment of loading for MM cartridges or external MC step up transformers.

MM RIAA phono corrector

two chassis construction for isolation of power supply


direct tube input directly coupled through shunt equalization
to a single triode output stage

[signal path is wire, tube, wire, tube, capacitor!]

tube rectified, choke input power supply
dual inductive filtering with permalloy [nickel] final filter stage

Supplied with 6J11 for V1, 5687 for V2

Alternate tubes:
V1 = 7788/e810F, 7721/D3a , 7722/E280F, 6688/E180F, 6J11, 6E6p
V2 = 1/2 5687, 6900, 7119/e182cc, 7044
V3, V4 = 6DA4/6DM4 rectification

gain, 42-48db depending on tube selection. 42dB with the 6J11 / 5687

input impedance = user defined
output impedance = 2000 ohms
max input voltage = 200mV RMS
max output voltage = 25V RMS

contact Jeffrey or Dave and we will direct you to your distributor...

thanks!

  1. Like the style.

    I also like "signal path is wire, tube, wire, tube, capacitor".

  2. bugger, i missed out on the first batch.

    units look cool as with most of the stuff on the product line..

  3. Any Plans for A MC version?

  4. obviously we believe in Dave's step-ups for MC use... but there has been talk of something "other" that drops in and runs off the same supply.. if you guys want to see this, send us an email...

    Peace,
