I think there were a few 350-series 4-tracks made. The guys on the Ampex
list will know who currently owns all of the remaining ones, if there are any.

The 300 transport would be no fun with 1/2" tape.

The thing is that 4-track was a popular format only for a very short period
of time. When 8-track came along, most of the 4-track machines were converted
down to 2-track mixdown decks. The 4-track 1/2" machines that turn up today
are mostly later machines used in the video industry.

I completely agree, that's why I'm trying to talk him into either a
440-4, or a 440C transport with 351 electronics.

440C with 351 electronics is going to require custom heads and a custom
cable assembly. Or step-up transformers mounted behind the electronics
units in order to deal with the low-Z heads. Playback would not be too
hard but record is going to be a problem.

Flux Magnetics can make heads with the much higher inductance needed to
match the tube electronics. Assuming I can get original cables, which
are (sadly) pretty critical for 351 operation, then I just might have to
change connectors at the head end.

The 440C would be my favorite candidate for a transport because of the
DC capstan motor, thus enabling synchronization and possibly even
locating with a synchronizer.

Oh, you can make up cables. Tektronix scope probe cable has capacitance
that is low enough for the job, I bet. And the original stuff for the
350 (I want to say RG-416?) is still available although it isn't cheap.

Flux Magnetics should have no problem making up the heads.... it's just
that they're going to charge you an outrageous amount for them. Contrast
this with ATR-104 heads, which you can probably pick up used for under
a hundred bucks each. My feeling is that the heads will cost you enough
that you could have just bought an ATR-104 flat and been done with it.

It's clean, but again if you're going to go that far, you might as well just
go all the way to the ATR-100 transport.

Hey... How about an ATR-104 with the Manley Steelhead tube playback
electronics? Those will beat the 350 electronics hands down. Play only,
though.

Hey, there is SOME sort of 350-class 4-track on Ebay right now. The Ampex
mailing list guys are mostly laughing at it but it may be worth looking for.

Ho ho ho.

A tube nut eh ?

When I worked on 350/351s we considered modding them to solid state !

I'm thinking low capacitance miniature video cable. It does exist. Dunno any RG
number for it though.

But it's not driven by *toobs* ! Therefore *can't* sound the same. It's a well
known fact !

And an ATR with my friend Dave Hill's Electronics, like Mike Spitz
sells, is pretty stellar as well, but this client wants the tube thing.
He's got a zillion input SSL, ProTools HD rig, tons of old analog
processors, and I just did a bunch of work on his MM1200, including
making it 16 tk, and connecting it to a Lynx synchronizer as well as to
SSL machine control.

But now he wants some tubes to record through as well. Keeps me busy!

And yes, the idea of an ATR transport with the tube electronics is a
good one as well.

Eccentric clients will always be with us. No point in reasoning with
them, just find them what they want and keep track of your time.

On a visit to Nakamichi's place in the LA area several years ago, I
saw an ATR-100 with home-built tube electronics (playback only, I
believe) in their listening room.

A lot of folks did this, and it seemed like a good idea at the time. The
Inovonics electronics, which seemed so wonderful and quiet, actually sound
really godawful in retrospect. Surprisingly the Ampex AG-350 electronics,
which were the first solid state electronics Ampex came up with, actually
sound pretty good. Dropping the AG electronics into a 350 was actually not
such a bad thing (although you had to change the heads).

The problem is that a lot of the multitrack 350-class machines were built
with the 354 electronics. And while the 351 electronics actually sound great
(if you don't use the mike preamps and you are very careful about setting the
bias oscillator up for lowest second harmonic), the 354 electronics are
really flaky. The 354 packages save a huge amount of rack space, though,
which was a plus at the time (especially with four channels).

Nowhere near low enough capacitance. The original cable is basically an
air dielectric thing. It's really scary to look at... huge cable with
hair-fine center conductor.

No, he's talking about dropping 350 electronics packages onto a 440
transport, so as to get low scrape flutter and the tube electronics. It
might not be a bad configuration, but it sure isn't a standard one, and
it sure isn't going to be cheap to set up.

I wouldn't call the ATR-100 clean. The fact that there's such a significant
difference between using the unbalanced output before the I/O modules and
using the balanced output from the I/O modules is worrisome enough. The
ATR-100 has really the best transport I have ever used, but the electronics
aren't any better than just "very good" to my mind. This is part of why
there is such an aftermarket of electronics packages for them, like the
Steelhead and the units that Crane Song builds for ATR Services. And doesn't
Millennia also make a playback-only package that will work on them?

Get him a stock 2-track 350 for a while and see how he likes it. They
are nice sounding machines in spite of the transport issues. If he wants
more channels, you can make him up a custom rig.

Ditto Scott on the 350's
Those were the first machines I worked with (we had three at the radio
station where I started.
I have two of the mono ones.

I was pulling your leg - as in the motor servo doesn't use toobs.
Thefore it can't sound as good. ;-)

Agreed about the transport. Funny how they didn't get better out of the audio
electronics. I seem to recall being unimpressed in that respect by Otari too.

Hey, I had a Fairchild turntable that way! Well, it wasn't a real servo,
just a relaxation oscillator made with a pair of 6L6es that drove the motor,
for very precise speed control. Well, not really all that precise, but sort
of precise.

Regarding that pesky Ampex cable, Studer finally solved that issue with
the head preamps on the 800. Now, the unbuffered [playback signal only
had to go a few inches to be buffered, thus enabling longer cables to
the actual electronics.

While the ATR is a wonderful transport, there is a certain aesthetic
about the older, more conventional transports that many people today
find "charming."

Right now my guy is looking at the 4 tk on eBay, so we'll see...

I have a 4-track 1/2" Ampex AG-300 in my basement, which was a stock Ampex
model using the 300 transport and solid state electronics. It still works,
more or less, although it needs a tune-up and some lubrication. I admit that I
have not measured flutter or speed stability on it. But tape-to-head contact
seems fine (based on reproduction of 15 kHz alignment tapes).
