Revox power cable help.

musicalstash · June 2023

Any idea where I can source a suitable power cable for a revox reel to reel?

https://ibb.co/RB2h69c

It looks like I need some sort of 3 pin plug it can't find anything suitable online.

Any help would be appreciated

Try the soundonsound.com forum, couple of chaps there run a lot of old Revox and other such kit

Ah, the old Bulgin PXO mini 3 pin...

Farnell or RS still do these - angled or straight.

I would say someone has bodged that from the original socket. That I am 99% sure was a square plug. Why for instance is that Bulgin socket back of a rectangular hole?

I 'may' have a plug somewhere so if you get really desperate, PM me but those 'bluggers' are no longer legal and if the deck were mine I would replace it with an IEC or if that won't fit, blank the hole and fit a fixed lead and grommet.

I'm inclined to agree, I worked on loads of Revox (A77 / B77 / PR99) back in the day and I don't recall the mains connections being like that.

Mini Bulgin. Illegal for mains these days I think… the full size ones definitely are. The minis are still used for 24VAC soldering irons and the like.

I also think it’s a bodge - from memory the original is a rectangular 2-pin a bit like a reverse US mains plug (but different dimensions), but I might be wrong. I think I have one somewhere, but I wouldn’t advise refitting one as it’s also probably not compliant with regs now. Better to fit an IEC.

Also, IIRC there is a mains microswitch interlock that you must defeat if you take the recorder out of its case?

Thanks for the comments and advice , this is one of two A77s I bought ( the other one has the two pin ) so will list this one as is and in need of work . I have not got the skills to swap the socket even if I could not too sure I should as I am unable to check if it is safe. Is there any reason they would have done the mod ? Thanks again

Probably because they lost the original mains cable.

I bought 100’s of PR99’s for work, a well known broadcasting corporation, and all were with IEC connectors. Might have broadcast spec version though.

I was in that Broadcasting corporation. PR99s were for editing use only - playout stuff was Studer A80, Telefunken M15....at least that was the case in late 80s

Yep. PR99's for office use and Studer A80's, and later 810's and 807's for studios. Plus old Levers Rich's....

If, as I am, you are averse to fixed mains cables and there is not room for an IEC. You could fit a short, 300mm cable and terminate it in an IEC male line socket.

Dave.

I did! 86 to 95 roughly.

Musicalstash, if you still want one of those Bulgin cables I have found one I made up years ago. PM me with your address and I can jiffy it to you. No charge.

Dave.

ecc83 · July 2023

Hey matey! I have the cable all jiffied up just need WHERE TO SEND IT!

If it still matters, I've found what I think is the original connector pair for this. It does look like it should be regulations-compliant, although I can't be sure. It's a nicely-made modern plastic connector similar to a smaller 2-pin IEC. (It might actually be a C9/C10, in which case it is compliant.) The cable on the plug part is only about 9" long but it would be sufficient to add a new inline IEC socket - or I could do that for you.

thanks , I was able to source a power lead from Ebay ...

I’ve seen a few Revox and Technics Reel to Reel machines years ago used on film sets with connections like that .
Not actually working as recorders or playback machines just spool turners.

Howdy, Stranger!
