Studer A80 versus A80RC MKII

The VU bridge on the A 80 RC is crap , at least my version .

Folks, I'm a bit confused and am hoping for clarification as I continue my quest for an A80. In this thread, I have read that the RC version is better than the A80 VU version and have also read that the RC version stinks - so I've got several questions on the topic;

- when you say the RC version is crap, do you mean for the RC and RCmkII? And, if yes, you're saying that neither the VU or RC versions of the A80 has good VU electronics, but that the RC version is the lesser of the evils?
- Are there big differences between the A80RC and RCmkII machines? I have a line to an A80, but manufacturer plate only says "A80 RC" - is the mkII something I should consider holding out for?
- Is the A80RC or the A80VU model older? I always thought the VU but read in this thread that the RC is older. That kind of makes sense to me since the B67 mkII shares an outwardly identical meter bridge
- related to the question above, could a B67 mkII meter bridge be successfully mated to an A80RC with full capability? I ask because I have leads to two difference A80RCs sans VU and I would personally like to have an original meter bridge on the machines

I've searched repeatedly on the topic and can't find clear-cut information on the manufacturing timelines of the A80 series machines anywhere other than snippets here and there from web forum postings.

Your insight and clarification is appreciated.

Hello Steve,

Understanding the A80 model family can indeed be challenging. It's a big subject. Unfortunately the web is full of misinformation about these important machines. I even see wrongful info posted here.

Again, I recommend the Studer list as the best place for getting authoritative, peer reviewed, factual information and answers to questions about Studer A80 (and A820) tape machines.

This is mine it says A 80 RC at the back

There seem to be indeed a lot of versions of meterbridges , i personally wouldnt even bother with it , and buy a A 80 without a meterbridge or ...a telefunken M 15 A

thought all RCs had ZERO LOCK ?
the trolley looks like ex BBC where the speed selector was down in front?
better change the bulb in RCH VU

this machine will sound better W/O VU bridge...I sold mine..and got one without
best

No.... the A80RC Mk I or II is not "crap". Yes, you can do better, but saying it's crap is a gross overstatement. I use outboard pre's as well as the meter since I also do lots of tape transfers.
I prefer the RC to the VU since it's easier to work on. Both transports are pretty much the same, just the onboard electronics. I believe the VU is a little "newer", but what's 3-4yr. when you're taking about a 30yr old machine. I like the RC since it's easily converted to use an outboard pre as well as internal and you can take it apart in an hour with 3 tools. I also like the RC better since I feels it's easier to calibrate.

I have lot's of extra parts for the A80 and A820 machines as well as pristine meter bridges that are looking for good homes.

Of course in the A820/810

my reply was meant for the counter issues on the A80 in the picture above

Dear Fred, I believe you could help a lot all participants here if you put your considerations about this two models here based on all your experience what, all us know, you are one of few most experts on this equipments on The world.

Yes, the subject of the A80 models was discussed in several en-lighting and factual messages with great contributions of Fred Thal and Martin Berner in the Studer list in 2002. They are still my reference on this issue.

Unfortunately who has entered recently have no access to so old messages. Last messages avaliavle on group date from may of 2010. 8 years later The message reported.

Should be great read this information here

It's disturbing to see published pictures of A80s (like the most recent one of an A80/RC here) showing the machine incorrectly threaded.

Obviously, the tape goes the other way around the edit slider bolt!

For anyone in the WBF community sincerely interested in the Studer A80, please see my final WBF post today, in the Studer list thread.

Thanks!

andromedaaudio · Jul 30, 2016

I dont edit and it doesnt touch the tape in the extension mode , i merely use it sometimes when i spool to prevent the tape touching the heads and makes noise , the telefunken i have does it automatically
Presumably thats what you meant ,

Assuming that you are a member of the Studer list, you can access the previous messages under the "Files" directory (in the yahoo Studer group). They are grouped together in text files (.txt).

I've seen an A80 threaded just about any way you can! Forget about the Preview machines... all bets are off!!

That's what these are used for!

Never to old to learn

Bruce, to be clear, 'crap' was a term I was reiterating from another member - I don't know enough about any version of the machine, nor have I heard it's output in person, so I can't form an opinion on it. I emailed you about the parts - call, email, or PM me back and let's chat.

No, that is not correct.

Your picture shows the record fader lifter pin. That lifter must NEVER be actuated in fast wind.

The same is true for the edit slider bolt (located downstream of the capstan).

What are the benefits of the expensive, straight-line headblock bypass seen on the A80 when people wrongly insert fixed-pins into the all-rolling tape path during fast winding mode?

Bruce B said:

Also incorrect information. While there indeed are different threading paths through an A80 preview headblock delay roller field, only the designated ones (for a given tape speed and lathe pitch controller) are correct.
