NTP 179 120 rebuilding (with porn).

[Valery]

Hi!

Long going to transform the quadro compressor of NTP assembled by Leonhard, using of the modules of NTP 179 120, VU meters NTP, transformers of JS and power supplay 24 V by Leonard.
This is original compressor, look like as a DIY progect

Here is some porn of it:

Here is a result of rebuilding

whoa, looks real nice Val,

on the last pic tho, seems like you need an engraved plate !, do a drawing what you want, and I'll get one off to you.
all the best,

Thanks Steve, I think about engraving plate too, but , unfortunately I will not be able them to avail from because of problems with receipt of parcel. I'll try to do it in Moscow.
Once again thank you. Valery.

Really Nice!

I have a stereo pair myself and the are really killer comps!
But mine are unbalanced and working in 0db level
So I´m looking for these JS trafos that make them work in +4db enviroments better
these trafo´s have the ratio 1:0,7 and 0.7:1

Do you have any ideas where to find a pair in and outs?

I have no any idea about this transformers, maybe I would try to sell old compressor, without two channels (modules, VUmetrs, transformers) but in working condition.

Maybe this datasheets will help you:

Glava, sneak through kubi´s site. There´s a bunch of info about old Rundfunktechnik trannies. Maybe you find an equivalent over there. Ratios like 1:0,7 or 1:0,7+0,7 were pretty widespread in lots of those modules. I might have some of them lying somewhere in the corner - mostly Haufe and Pikatron (but no JS) - if you do not necessarily want to stay with the original JS.
