« on: April 06, 2005, 04:13:15 PM »
on the part list I have 4  47u 50V  RAD.EL.LYT     TRIPLER P48
but on the pcb it's written 47u 63V

which one is right ?
( I bought 50V , would it work ? )

same problem with C3/C103 which are 470nF on the part list and 220nF
on the PCB !!!!

except that my first day of soldering was cool !  :grin:

sorry guys I have a new question !

about the relay,
No way to find some 12V 2xCO

someone told me to take 2xRT and he didn't know what 2xCO was !
anyone knows where to find 2xCO in europe ?

( I'm nearly done with it !  :grin: )

Thanks

I see what you mean
The parts list says
12V 2xCO RELAY

What that means is
2 lots of a "change over" relay
e.g. DPCO or DPDT (x2)

Yep ! Sorry Ethan !

When I first posted it I thought it was in the lab
Once posted ( and it took me a few time to realise )
I saw it was in the black market !

Tak, Thanks, Danke, Merde :shock:

Can I use 0.6W resistors on the G9??

Can I use a 50K log pot for the "output level" ???

Just use an Omron G5V-2 - very easy to get (from Farnell, RS, Elfa etc.).

Yes. 0.6W is standard around here now.

I just finished my G9 a few days ago and when I tested it with my RME converter I got a Bzzz sound at -40-50 dB on both channels - the strange thing is that if I turned the power of the G9 and recorded I still got the Bzz sound so something is "bleeding" even though the pre amp is turned off!!
   I'm going to work on it today so I just want to hear of any of you has some advice where to look for the problem??

   I have grounded the 230V power input to the chassis and I have grounded the input XLR's at the grounding pin on top of the Neutrik XLR's and then I have connected all 4 XLR at pin 1.

   I can measure around 9,5VAC on every pin on the XLR's or on the top of the OEP/Lundahl trafo's

Any advise where to look before I start to take everything apart??

... and if I only measure with the negativ (black wire) pin from my multimeter I get around 2.5VAC???

are you using grounded mains power? that is, 3-pin mains plugs into wall socket with ground?

also try connecting the two chassis's with a piece of wire to rule out potential differences.

These problems probably comes from the power inlet filter in the rme - you NEED to run it on grounded mains..

No I'm not using gronded mains!
...but I tried to connect the the gronding pin on the power input to a radiator  and that only enhanced the Bzzz sound??

As I said, I think it's the RME, not the G9..
