ED8000 SE or Parafeed?

[alexg]

Has anybody done an ED8000 SE or Parafeed?

Can you share the schematic?

I am planning to build an ED8000 driven by either a 6dj8 or 6n1p in SE or Parafeed.

Opinions and advice will be appreciated.

Thanks.

I have some pieces
of ED8000
looks realy good...
small and compact
*
I need a little amp which could be easy to set
and with no complex OT at all
thinking about ED8000 or 2A3...
*
settings for ED8000
*
heating 6.3V/0.8A
RL=1500 ohm
Lp=9H (8Hz -1db)
Po=3W/4W
Ua=154V/167V anode voltage not Vb,
Vb=Ua+Ug+drop at OT
Ia=100mA/90mA
-Ug=30V/35V
Rk=please calculate...
Ck=experiment with 220uF to 1000uF
-A=2.9
Cdyn=44.5pF for choosing the Ri of the input tube...
S=17mA/V
Ri=225 ohm
mu=3.6

cheers

actually it is maybe the best of use for the RIAA preamplifier
in LW mode Rloaded...
extremly linear, low out Res. and lower Vb alowing loftin-white mode...
