vermona ET6 flute filter kit - passive RC lowpass

Post by trouby » Thu Sep 20, 2012 12:53 pm

hi,
for the DIYers I have a bit crazy idea:
i found the schematic interesting of the passive RC-lowpass filter bank of the GDR organ ET6 from vermona.
i attached the original and cleaned schematic without the values :roll:
the filter has 6 octave lines and each octave is splitted in 2 filters - the organ has splitted keyboard to bass and treble - left is bass and right is treble with 3 inputs.
i called the bass input A and the 3 treble B, C, D.
makes in summary 24 inputs.

kit contains:
- NOS styroflex capacitors
- resistors
- 2 1/4" jacks
- manual in paper and pdf
- pcb
- 24 pole switch

you need a pre-amp. the filter is complete passive. level drop is 50 or -43 dB.

price:
$ 100 total incl. shipping - drop me a line for ordering.
limited to 15 pieces.
