ok now some little history ...

this console was buy by "radio france" in 1978, and wired in the "studio F", final diffusion room for "france music", the french classical radio.
After 12 years the console was sold, and owned by a "radio france" tech in 1990.
2010 i am the third owner

cleaning all modules and start to reload the frame ...
take lot of time cleaning all electronic board, all caps
i also do a visual check for electronic component, soldering, and counting all electrolytic capacitor for a future recap ...

i take around half an hours for each card ...
-aprox 40 audio card on the console back
-24 input modules (the vertical front board), pan/aux send, Vu meters, etc
-32 main frame modules, comp, rev return, preamp/eq, master select, and some blank modules ...
-32 smal main frame, fader etc ...

Cleaning finished !!!

Everything is loaded (except Dual 6w amp card, making on of the 21v stab shutting down...)

As you can see one of the four armrest are missing, i will ask for a mechanical workshop making me a new one, seems easy to do, only 3 aluminium pces and 2 plate.

And i use one of the stereo fader (loaded in rev return 1) as spare part for all other (missing screw etc ...), so i have to find 1 or more new fader ...

About the fader, it's one of the challenge here, finding carbon or conductive plastic track replacement for the 32 fader (6 mono 13 stereo), lot of the stereo one are not matched anymore.

Now its time to fix and repair the electronic...
testing everything i can, and try to locate all the pb
The console was not powered on in the last 15 years ... i let you imagine what that mean.

I start to do the part list for all electrolytic capacitor ...

In that third picture, I see you are using a flame torch to deal with the "heat shrinkable" tubing. Wow...I use an electric heat gun which was sold to soften paint so it could be scraped off. Flames worry me <grin>.

Best,

Good new

i just realized ... the whole monitoring section are not wired as the wiring list say

i think i have the wrong manual (cause soldering seems original on the relay card)

some of the manual wiring section say 1.289.043/044 (console version) and the wrong page say only 1.289.043
so maybe "radiofrance" buy 2 (or more) console, same config except monitor section.
i have the 1.289.044 version console, i think...

Time to track and relist aprox 50 push button activating 50 relay. And see witch audio signal are controlled by each relay ...hundreds cable

i love this game

ok!

i need some little advise about electronic components

first:

op-amp lm301an

i find this:
National Semiconductor | Semiconducteurs | Amplificateurs et Comparateurs | Ampli-OP | Amplificateurs opérationnels (simple) |LM301AN/NOPB
nopb verssion, are this one 100% compatible with old one ?
its the same manufacturer as studer use in they board (NS).

second:

power supply electrolytic condenser:
4700uF 50v "condensateur de lissage" don't have english word, the one just after 4 diodes bridge, used to transform positiv AC to "aproximativ" DC (have a regulator card after this stage)

i find this:
BHC Components | Passifs | Condensateurs | Aluminium | Fixation de type serre-joint - séries ALT22A, ALT23A 85°C - Cosse à souder |ALT23A472BB063
reasonable prices, screw mounting chassis, soldering contact, as i need...

and see this:
Vishay | Passifs | Condensateurs | Aluminium | Borne à vis - ALS31A, PEH200 85°C |MAL210658472E3
no comment about the prices ...
screw mounting chassis, screw contact
are this one really better ???

TKS!

TKS!

that LM301AN is the same, if not better, opamp as the original. the additional suffixe (NOPB) makes no electrical difference, it means no lead (No Pb, Plomb! Oui je parle français! t'es chanceux, hein?).

Now your condensateur de lissage is simply called a filter cap. And I donT' know why you would spend that much money (9 euros?) on a simple capacitor. I'd use this Phycomp | Passifs | Condensateurs | Aluminium | 2 broches, 85°C |LH050M4700BPF-3025 unless you need the bolt on the end to secure the capacitor to the chassis? does the original cap have that bolt?

what does the original look like? Is it in the pictures?

cheers,
2N

by the way, beautiful european console that Studer!
