He said 1-million not 10-million.

Is still in progress.......

Actually we will receive in a few weeks the first proto-batch. The design is made on a 4-layer PCB, so it's more complex as the UcD180 / 400. Unfortenatly it take more time till we have the real production version ready.

There are already more as >1.000.000,00 channels produce with the same coil as in the UcD180.

Jan-Peter, it's unbelievable!! 100 millions UcD's which have the same coil, and seems there is some quantity with other coils.. Where is this ocean of the UcD's, on the stock? All this UcD's put one by one, would be way from you to me and back again, i'm sure..
100000000 pieces it isn't wrong?

Sanders is right I wrote 1 millions.....

However Philips is using the UcD design in a lot of there own products. So I think this quantity must be probably entering more the 10 millions quantity. Don't forget that one Home Theater Amplifiers means at least 5 UcD channels

JP, which resistor to change the gain? Was testing 1 but it is amplifying too little for my passive preamp. Gain should be about 6ox for me. Is this 35Db?

Jan-Peter,

Thanks for the update.

Hey Jan-Peter,
I am more excited about the UCD700 than Jam, so bear with me. Can you give an estimate as to when the UCD700 will be ready for sale, maybe a few months or so?
I have two 1.5KVA transformers waiting to be used.

Thanks
Lawrence

Indeed in a few months.......

Please keep the transformer free for two UcD700 (or 1000?)

Resistor R3 (value 560), straight to the small side of the OPA2134/AD8620.

The gain is now 26dB, when you decrease R3 the gain will increase.

JP, should it become 180 ohms for 60x gain? I don't know how the gain system in the UCD is done.

Jan-Peter, I see at your homepage that you are soon going to release power supplies for the UcD amps. Could you maybe publish a bit bigger pigger pictures for us who can't wait.
