Re: [ARSCLIST] Revox A77
Hello, Peter,
Affording and/or getting a fair/good price on an A77 is one question, 
the overall desirability of that machine for archival work is 
questionable today. Since you refer to yourself as a "babe in the 
woods in this area", please forgive me if I over simplify this.
Please don't get me wrong, I made many lovely recordings on my four 
A77s (I still have two, one working well), but I don't find a place 
for them in my restoration and transfer work. The last time I used an 
A77 was as a trial machine to see how cold playing would work on 
squealing tapes.
First of all, the A77 is at least 30 years old. There were at least 
four different versions of the machine (Mk 1 - Mk IV) and IMHO, only 
the MKIII or MK IV are worth getting (my good one is a MKIII). But 
these are 30 year old machines. Most, if not all, of the parts are at 
least 30 years old.
Second, what shape are the heads in? Even before that, what heads are 
in it? Quarter track stereo or two-track stereo? Many machines that 
might be "creampuff" candidates I suspect would be quarter track, 
sold to consumers who took care of them. Most of the two-track decks 
were used professionally and are probably worthless today except as 
parts donors.
See the following link for track information.

There may be some NOS parts available, but changing out the heads 
would be a multiple-hundred-dollar effort if you could find the heads 
or an appropriate substitute. If you have to buy new pro heads 
(because nothing else is available) that is a couple of hundred a 
head, would be my guess, not counting installation.
Third - The A77s definitely don't play back as well as they record, 
and they are not the most gentle transport around. These are constant 
torque rather than constant tension machines.
If you're spending in the multiple hundreds of dollars, you might 
consider an alternate machine. Some of the B77 or PR99 ReVox machines 
are newer by a decade and may be a better choice. If you're lucky, 
for half a grand you might find working pro machines such as the 
Studer A810 (though these go for more than that now, but I've been 
lucky in the past), or Sony APR-5000 which is one of my two favourite 
tape machines for many reasons.
But with any machine, even if it starts out as a mint creampuff, will 
need service work. How will that happen?
I would need to understand your goals in acquiring and using this 
machine far better to make a recommendation.
Good luck. I hope this helps a bit.
Cheers,
Richard

Can anyone give a rough guesstimate on what a Revox A77 in 
(supposedly) perfect condition might be worth on the market? I know 
that it is worth whatever one is willing to pay for it, but I could 
use at least some guidance based on what someone may have laid out 
for one in the past few years. A quick search seems to confirm that 
this model can be taken seriously enough for my personal purposes, 
but I need to know if I ought to make an offer in the low hundreds 
or think bigger. I can probably afford whatever is asked, but I'd 
rather not spend foolishly.
I am looking for a fairly decent deck and found out about one of 
these that is for sale locally. I would like to be able to either 
make a reasonable offer (on the low side) or know if the seller is 
setting the bar unreasonably high before I make contact with the guy 
with the deck. I'm totally a babe in the woods in this area, so any 
sort of crash course information on evaluating used Revox decks 
would be most appreciated.
