Happy New Year!
Thank you for your answer gyraf . Well I'm using this VU http://www.ebay.es/itm/130384936913?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649and compression makes me correct data but the VU meter mark wrong, I was checking the voltages of the transistors and are within the margin, resistors too. From the list of COMPONENTS found one that not to put it:65 1 8.2K resistor R50 (Not Used in Gyraf version)because I don´t know where and I make the J rev.¿Can this be the problem?
It's right there in the ebay posting you linked to: "no external resistor,diode required,"These are probably the stock Nissei meters that don't conform to the normal VU standards. So you'll have to modify your build to accommodate it.
I found this topic:http://www.groupdiy.com/index.php?topic=1996.0Some useful information but i just started to read it.Maybe together we find the answers On nissei site i didn't find anything useful.
If so, it's only 3.6KΩ in series to add.

In what capacity is the capacitor?I discover the metter have a diode rectifier and a resistor of 1,5k but I think the assembled components are of poor quality and no resistance when combined with the 3.6-k
Yes, I think You should use an external 3.6 K. The PCB is part of the regular circuit, which is used with meters, that have 0dB = 1.23V. You need an additional 3.6k, to get the 0dB = 1.23V.
