A gent sent me this link wanting to sell his 10A Line Preamplifier. Thought I would mention it here.
The 10A is only one of three preamplifiers listed in the Exceptional Catagory, mid 2000s, of Bound for Sound.
Other reviews.
"Bound for Sound, Issue #163 SAS Audio 10A Triode Preamp is one of only 3 listed in "Exceptional Merit" catagory. "I expecially feel that way about the SAS 10A, a tube unit of moderate expense that simply stomps a mud hole in just about every active unit made - regardless of price."
"Rich Weiner: "The SAS 10A is the most musically truthful preamp I'm aware of, and I will expand that statement by listing some of the line stages I've had in my otherwise very stable system: Herron VTSP-1, VAC CPA III, VAC Standard LE, Audio Research 3A, ARC 8, ARC 10, Mark Levinson ML-1, Levinson ML-7, Levinson ML-10A, Original Aronov PS-100 and Musical Concepts modification, Nagra PL-P, Beveridge RM-1, Rappaport, Placette Passive - there are more, but you get the point. Until I got the 10A, I struggled to make the other components live up to their potential." The 10A has been Rich's reference preamp for over 4 years. However, Richard now owns the 11A preamplifier as his reference preamplifier.
"Eric: "The 10A excels at tranparency. Not in the sense of being overly analytical, but in the sense that you hear the music as if it was live."
"Bob: "I liked this preamp…a lot! When I first turned it on, it seemed a bit dark and lacking in air, but in the next 30 minutes, the change that took place was amazing. If there was one word I would use to describe my experience with the 10a it would be evocative…or compelling. But wait, that’s two words isn’t it?""
(I never sold a 10A that was a floor model or store returned.)
When shipping, I would suggest United States Postal system.
I can send an owners manual via email if one if the seller does not have it.

I think it’s likely to be a very, very good preamp. But I’m tapped out right now with moving expenses and it also doesn’t have a remote, which is a necessity for streaming and I want the convenience as well.

Why sell perfection? for cheap?
seems wrong
maybe its a scam?
seems shady.......

Cmon
that was like a setup!
It was to0 easy....

A close pictorial inspection reveals it has a captive power cord, so one of my first units.
I do not know the Gent selling it, but I saw this:
Seller information
rtboy10 (3947)
99.8% Positive feedback
Pretty high positive feedback. Anyway a friend from near by sent me this:
Hi Steve,
Seller asking $1100 plus shipping.
Linny
and I thought I would
pass it on.
cheers

Positive feedback means he sells many things, I think the number 3947 means how many transactions he has done, so he sells a lot of stuff
Thus info has no affect on the pros or cons of the preamp , only that he sells many things.
I have a friend who does the same thing, buys at estate and garage sales and flips them for huge profits
Ever since American pickers a whole subculture of people have developed from this show that do exactly the same thing.

The 3947 is the feedback the seller has received from customers. With such an overwhelming positive
score of 99.8%, that indicates the seller is honest.

I do too Nick. He was the most honest gentlemen, especially considering his position with BFS.
He lived what he "preached" from all I have read and my dealings with him.

You mean the seller offered to reduce the price without you asking?
I smell a scam, if that's the case
I put up a preamp for sale loaded with Dave Slagles autoformers and output transformers, I must have received 35 emails with people offering me MORE than I was asking, I decided to keep it.
-
Sorry, I'm not an ebayer..

It was sold and the purchaser is sending to me for a check up.

Any thought of possible upgrades you might offer the purchaser Steve? An IEC terminal & power cord maybe? Is a remote even doable? Or is this a case of why mess with perfection of which I would totally understand.

Steve,
I would be interested to hear regarding potential upgrades as well.

Sorry late as dealing with mom's nursing home etc.
I found the 10A to be slightly light/thin in sound.
1. Changed the power supply decoupling cap for slightly more bass.
2. I am adding another stage of filtering, so 6 total stages. Using a very high efficiency horn and
powerful amp, one might detect a very slight 120 hz hum.
3. The buyer wants less gain, so I am setting up the output for approximately 9db of gain
rather than 21db of gain. The noise floor is reduced by another 12db.
The new owner doesn't want an IEC connector installed, although I can. The newer models already have
an IEC connector installed. No remote option. I could install a small value balance control in place of one
vol control so balance altered a few db.
I am almost thinking of resurrecting the 10A or 11A, but I only have the black 10A chassis and no silk screener
or other letterer. The price would almost certainly be higher as well. I am pretty tired as it is though.

Interesting upgrades, Steve. I’m surprised that your client wouldn’t want an iec connection. If you were to resurrect the 10a and/or 11a, I would think you might lose some sales because of the lack of remote capability. As to no silk screening, you or your clients can have very nice plastic or metal pieces with a design made very inexpensively and they look great. I had a couple made up over the years and was very pleased. There is a guy over at AC that does them.

Hi Nick,
I forgot to mention finding accurate poly capacitors. An IEC and different power cord doesn't make a difference in my
preamplifiers due to the complete isolation provided by my PS filter stages. I suppose there could be a sonic change due to L and R channel musical signal current return through pin 1 (ground wire) of the power cord, from component to component. But it is easy to minimize/eliminate.
Installing a remote would require a completely different chassis and cause sonic problems. There are plenty who don't care about having a remote.
I cannot email on AC, and limited posts.
cheers

Hi Steve,
As to that iec, your excellent isolation design might well circumvent the need for a good power cord. I was one of those guys though who avoided buying Van Alstine products because he only offered a captive cord. When he finally changed his mind, I bought his AVA SET 120 amp which was quite good and a bargain for the money. As far as I know, my superb sounding Supratek preamp uses an Alps motorized pot. I would not have bought it …no matter how great it sounds… without remote capability. I can easily see a manual pot for a vinyl aficionado or one who plays one CD at a time. But I stream and the variation between the volume from disc to disc is quite a bit. Thank goodness I have a remote as I wouldn’t want to have to jump out of my chair each time so the neighbors wouldn’t be bothered.
I don’t know how doable it is for you to resurrect those preamps, but I’d think you’d sell enough as there are many like me who are very aware of the product line.

Hi Nick,
The early versions of the 10A did not have an IEC, and this customer did not want me to install one
on his as he understands that it won't change the sound.
After the early version, I did install IECs standard due to customer demand. But then,
installing one does not affect the musical quality of my preamplifiers.
Other brands it will.
My designs are totally from scratch and unique, even if portions of the designs looks similar.
I tried the alps and you will Not find one in any of my products. Enough said.
If one wants the same old sounds (always missing the mark), there are plenty of other brands,
and the same old designs out there. Another reason why I retired.
Of course with my pre, one less component that will alter the sound.
To maximize total performance of one's system, one will have to upgrade the rest of the
system. Synergy only helps to a point. Best to improve the rest of the system as well.
By the way, I just experimented again by installing a 12pf poly cap (12 x 10 to -12th) across a 50ufd
crossover capacitor (50 x 10 to -6th) and the sound zinged bright.
That is ~1 part in 4.1 million. If we relate to voltage change, that is -132db.
Typical +/- 0,1db from 20-20khz is only -54db. The -132db is 6200 times more sensitive; hence, the
incredible ear.
No wonder components sound different by different manufacturers.

crossover capacitor (50 x 10 to -6th) and the sound zinged bright. If we relate to voltage change,
20db change per decade, the bypass is -132db change min. No wonder components sound different,
even with the same specs used by different manufacturers.
That correlates with other minute changes in parts values in the crossover.

Thanks, Steve. I think an iec is always a good idea as it gives customers a choice. As to that Alps pot, I’ve read a few negative comments here and there. Occasionally I look at owners comments regarding my Supratek Chardonnay. I don’t recall any owners suggesting a change to a different motorized pot. Maybe it is because of lack of room in the chassis. If I could get this great sounding preamp to sound even better, I would do it.
Do let us know what the final result is with your experiments.
Nick
