Hi guys!
Here will be posted info for 33609 builders.Will try to help with this when have free time minute  Take some patience for my english Please note, this tread for education purpose only. I can't care for any damage etc if you throw this unit onto your neighbour from 9th floor, electricity shock, so on. PCB's and cases were offered there. http://www.prodigy-pro.com/diy/index.php?topic=25172Complete manual: (right-click, save as...) http://www.ams-neve.com/downloads_all/files/Outboard/33609JD.pdfSchem for reference: http://i251.photobucket.com/albums/gg291/diy33609/33609_SCHEM_VOLT.jpgErrata: If you look at the signal output, on the right of the pic called "33609_SCHEM_VOLT.jpg", the numbers differs from the PCB. 1 HI 2 GND 3 LOW THIS IS CORRECT...

In case of use of 12v relays, put 12v jumper to connect relays in series, if 24v relays used, put two jumpers marked 24v for parallel connection. Jumpers are located on top side of pcb beetween relays, they looks as smd pads.

Hey Igor,
thanks for offering this project - I'm seriously excited about building this. Are we locked into using Lorlins for everything but the threshold switches? I'm building one of mine with original iron and I'd like to go Elma all the way. Is the only way to wire off the board or is there a high quality rotary that shares the same footprint as the Lorlin?
All the best,
Ruairi

Thanks for the great project.
Before I start building mine, I was wondering what the options are for audio transformers. Is it possible to make a short list of compatible transformers?
And are there any side chain options? Couldn't find any info on that topic.

T2 is a step-down transformer 10k:2k4 / ~2:1, TF10016, L31267 or similar
T1 is a step-up transformer 1k2:4k8 / 1:2, TF10015 or L10468 or similar
T3 is step-up transformer 70:600 / ~1:2.5 (+8dB) TF12009, L1173 or similar.
If you use an outputtransformer with an other ratio your limiterthreshold will not track as the limiter section is made to be feeded from a low impedance sorce 8dB below the outputlevel.

Regarding trunny's, psb fits TF10016, 31267, OEP A262A2E, LL1540,
LL1532 as input, TF10015, 10468, LL1528, OEP A262A2E as interstage. Some others can be used too.
There's enough "spare" on trimpot RV1 to give same output with 1:2
output trunny, and limiter section can be adjusted to track properly.
Just use RV4 50k instead of 10k.

Any good places to find those vintage transformers for the original feel?
If I'm correct, Sowter would be possible too:
T2
Sowter 9165 (2+2:1+1, 10k/2k4, +24dBu)
(replacement for 31267 according to Sowter)
T1
Sowter 9145 (1+1:2+2, 1k2/4k8, +10dBu)
(replacement for 10468 according to Sowter)
If you can't find original xformers for T3, what would you guys recommend?

Igor,
what size does the power transformer need to be in VA?
24v i'm assuming?

There's a lot of output trunny's which can work fine and sound
like a charm there. Edcor, UTC, Sowter, possible to use API output clones...it is all up to your taste.
Not necessary to use 1:2.5 ratio, 1:2 trafo will work fine there.
For power supply trafo, 24v 1a, toroidal trunny preferred.
Power supply diodes, generally 1n5400 kinda stuff.

Here is the place for some usefull tips on this project.
Not necessary to use Elma 24 pos switch on limiter threshold.
For most situations, 1dB steps are just fine there. Good way to save 20 eur.
Unit done with original trunny's should have very close to original sound.
To have a lot of distortion coming from saturated trunny's use
OEP A262A2E as input/interstage. Great distorting box for drums.
Use transistors with same order codes as in BOM. BC184 and 214
comes in different pinout versions. We need CBE version.
Check everything twice when soldering PCB.
Properly soldered unit works from first power-up
and just needs about a hour to comlete cal. procedure.
One reversed bastard or wrong nominal can add some
hours of headache.
See photos, it will help a lot to localize parts and their placement..

Maarten Maybe the Carnhill CA-18-VTB1847 (LO1166) CA-18-VTB9057 (LO2567) CA-18-VTB1148 (LO1166) CA-18-VTB9049 (same but narrow board version) Could be used, Don't know the exact turn ratio's But they're not that expensive (about 17 Pounds at AML) http://www.technicalaudio.com/reading/neve_xfmrs/neve_edo7113.html |
