Old Equiptment found - looking for information as i would like to repair it.

[Blakethursday]

Hey everyone,

I am new here and joined as i have recently fouond and purchased an old, what we think is a 70's recording desk. all signs are that it is from the 70's but we are unsure.

i ahve taken some photos and i can explain in more detail anything but here are some pictures of the beast. do you think it will still work once we add some inputs and power box to it.

First of all in the future please don't crosspost. That means cutting and pasting the same message --- or posting a similar one --- in more than one forum.

Judging from the cabinet making skills in the overview picture, you've got something homemade there.

Whether what's inside has survived the intervening years - or was any great shakes in the first place - is what's at issue here.

If had something like that I would take it in to my local repairman --- who's probably not too busy these days with disposable everything being the rule in the audio world.

sorry for cross posting, i was unsure as to which of the 2 boards i should post this on. We can delete one if you like.

my thoughts were that it could have been home made but all the electricals and wiring were done so efficently and well we second guessed it.

i think once i get some power supply to this thing i could check each part separately and see if they work straight from that. and then move from there. or do you think it would just be much easier to take it to an electrician. and get an overview from them - the only thing is that will cost money just for them to look at it. cant i go though and look at all the parts and then see what needs fixing from there?

hi.........
prior to plugging in, have u thrown a multimeter acrooss the ac plug to check for a dead short or bad earth, ...at the very least?

You might want to post questions at these sites (mainly in the prodigy-pro "the lab"):

Good luck! You have some interesting stuff there. At very least you have some interesting looking components.
Also, that looks like it was originally designed for broadcast mixing.

Super spit - Unfortunately no ac plug on the desk. We have to ad dour own, which means going through and checking all the volts on parts so we dont blow them.

What you have there is a radio broadcast desk. That might help narrow your search.

[zradioman]

Indeed it's a radio board. . .maybe a Harris? If it is, you've got yourself a nice little unit. . .looks like mono though. . .either way you may have some good clean pre's. We just got rid of a similar unit with the wood grain wrap. Clean it up, maybe a rewire, and use it (or sell it to a podcaster).
And Hey, if you're diggin around and you run into a DBX 160 VU, I'd be happy to take it off your plate. . .came across a matched pair last week! NEEEEEHAWWWW

[PinkNoise]

Can't help wondering where you live. Those VU meters look very much like Australian ones from Masters Instruments. They are labelled with the options of LEFT and RIGHT so it doesn't look mono to me. Good luck with your restoration.

To my newbie eyes it looks as if it's been refurbed in the not too distant past.

I see DIP/DIL IC's (were these around in the 70's?), some new looking diodes and electrolytic caps etc.

I'm no expert though by any means, they guys at the Lab may be able to tell you more.

[mshilarious]

I think I would gut it for the nicer parts. The ICs look like TL07x and 5534s, nothing wrong with that but mixers based on those chips are hardly rare. You could buy yourself an A&H MixWiz for a lot less trouble.

I think I would strip the VU meters, some of the switches, and see if the mic transformers are good. If so, take a couple of the channels and built that into a rackmount pre.
