and Bobby" heat mod to keep modules cooler...Send me your email and we will connect. I can tell you how to get the most out of your VR and where not to spend money or time... cheers (insert smiley face here)
We have smart thermostats and warning lights in our machine rooms. The smart thermostats email the manager if temp or humidity exceed a threshold and the warning lights notify staff of extreme conditions. We’ve had condensation issues, too, so now we keep small dehumidifiers running in our machine rooms. Our big machine room has a traditional hvac system plus a smaller split system as a backup.I was working at a facility with a single large AC unit in the machine room. The AC unit failed & it was a big problem to put a temporary system in while waiting for parts. They had to make a panel with a hole in it where the door was to evacuate the hot air from the temporary system. In some ways it is better to use 2 smaller systems so that if one fails you're not left with nothing.
I concur. Ams/neve designed around the 5532/34, it’s a known solid chip. No need to change it. Plus most changes are not as noticeable until you hit distortion land. Or on some cases cause oscillations and other unwanted issues.I wouldn't even change 5532/5534 chips to a different brand or different production date needlessly. This console was designed with exactly the chips used in mind, making changes is asking for trouble. I've been there too many times... Don't change normal electrolytics for low ESR either, same thing. Don't just add any decoupling caps anywhere or change the size of PSU decoupling caps, again, potential trouble. With a system this complex you can search forever for the problem you inserted...
Been there and done it… then the fuse cap pops out and falls into the wiring in the trough. No one can find it and now someone has to drive to the electronic store or steal one out of another piece of gear to keep the session running… hahaI concur.

As for complexity yes, they are. Another tech I worked with got into the habit of working on the desks with the power on. Usually not a big deal as you can hot plug a module. Not a best idea but it can be done. Anyway while working the aux master module he managed to short it out when putting in back in. We lost ever aux master. After going over schematics and the board. I found the first best start to what went, a fuse. It was on the schematic. Took a day to find it as it was physically located no where near the aux masters.

I think I i'm right in thinking that the V series was the first digital desk Neve ventured into.
And the one that the heat generated by all the ( CHIPS ) EMPLOYED took everybody involved by surprise. !
I Remember that a chap called Andy.! did some calculations and found the power consumed by the desk. was over 1.4 kwatts
Now ! without the use of forced ventilation. No ( Fans ) allowed in the studio. Getting rid of the heat was a nightmare. .
I had to go back to basics, HEAT always rises. !!!
Hence the under tray of the console was cut out replaced by open mesh. The under desk trunk with all the module connections are . had the rear panels ventilation holes . added.
Top back of console had large vent slots added. That still didn't give enough cooling. !
Leaning over the console i realised the heat was all coming from the individual modules. and due to the angle of the modules it could not get away. ( Way to hot to touch. ! )
Hence i had to get the surface heat away. !
That's why all the pots. ! have a moulded ventilated support mtg. under the knobs. Holding the knob up by 2 mm to leave an air gap.
and the faders are spaced off top section by 5 mm and the fader slot in the panel is 5mm wide. leaving air gap. and therefore needed extra long knob mtg. shaft. allowing air to get up.
After many nights of trying different fixs ( development was over mid summer and days were very warm. so coolest temps over night., ) LARGE multi channel temp. recorder all connected up. !
So it was all near the bone stuff.
The cables from modules back to main bus bars were found to have better air flow over them. by not being t fixed back to a big mtg channel. ( plus it improved cross talk. immensely. )
Be interested to know how many of the V series desk are still in operation. ?
Hope this helps.
Catch up later
cheers

Over the decades I have used truckloads of Bifet TL07x. In my experience properly applied (modest gain and lightly loaded) these op amps are transparent to line level audio.I wasn't aware that there were that many 074s in a V, wow!
In a similar vein, my ADT console makes use of plenty of RC4558 op amps. Replacing those with 5532 oder better doesn't do anything useful but increases current draw. Thanks to thoughtful use of op amps this large format console gets only warm but never hot and works with a passively cooled external PSU.Over the decades I have used truckloads of Bifet TL07x.

Always wanted to test drive an adt desk. Sadly I do not know of any on this side of the world.In a similar vein, my ADT console makes use of plenty of RC4558 op amps.
