How much money are you offering with the 3630?

Really, why do you think I'm selling it. I never even
bough it in the first place, it was given to me. People are buying them
and modding them, though. It was a recent TapeOP, I think, that had an
article about modding the 3630, and turning it into something usable.
I'm just not interested in taking the time.


There were two modifications written up in Tape Op recently. One
(which I think may have originated with Dusk Bennett or someone we
know form this newsgroup) involves disabling the gate function. The
other, which was reveiwed in the current issue, is the Black Lion
Audio modification, which is much more extensive.

I was hoping to be able to report on that mod, but I still haven't
heard it. A while back when there was a discussion of the Black Lion
3630 modification here (mostly about how difficult and time consuming
it was to do the work) I offered to do the work if someone sent me a
compressor and a kit, so I could give an objective opinion of how
likely someone would be at successfully performing the mod. I was
going to pass it on to Dave Martin to evaluate as a compressor since
he has more compressors than anyone I know, and maybe we'd get a
magazine article or at least some newsgroup fame out of it.

Anyway, Andy sent me a compressor and kit, I spent a full day changing
out the parts (actually two half-days) - it involves replacing about
half the components on the board - and when I hooked it up, I was
impressed with the fact that I could barely hear it working. Well,
that was because it barely WAS working. Although the lights on the
panel indicated that it should have been compressing heavily, and all
the controls appeared to work, according to the on-board LED meters,
at the most extreme setting, I could get only about 1.5 dB of gain
reduction.

After some e-mail correspondence with the Black Lion guy (I had
already pretty much gone through the troubleshooting he suggested) and
being really sure that I hadn't made an error (both channels behaved
the same way, so if there was a mistate, I made it twice), I sent it
off to him for a look-see. He confirmed that it was indeed behaving as
I had described, and said he'd have time in a couple of weeks to see
what was wrong. Months later, he told me that he discovered that he
had to change some time constants but that it was working pretty well
and he was just about ready to send it back. That was two months ago.
I don't think he's a flake or a cheat, but this is a side project and
he just doesn't have time to do commercial level tech support (because
that's not what he is). I guess it's time to write again.

He used to offer to do the mod for a bit over $100, and that's a great
deal, if a Black Lion 3630 is something that you can use. John from
Tape Op seemed to like it, but he copped out and had someone else do
the modification job.

Perhaps one of these days I'll have more to say. Fortunately, the
owner of the compressor is patient (he replaced it with an RNC).

There is a recognized minimum monthly requirement of turd polishing.

I owned a 3630 in 93. Used it once. Never turned it on again. Don't
consider it worth modifying.


So only gear that's already good is worth modifying?

For the most part, yes. You take something like the 3630, and the input
and output stages are junk, so you'd need to replace those. But the
power supply is cheesy, so you'd need to replace that. The gain control
stage could use some cleaning up... and the control logic is just total
crap so you'd need to do that. While you're at it, you could clean the
PC board layout up a little. Next thing you know, you've spent thousands
of dollars and it would have been easier just to build a new compressor
from the bottom up.

That's why I wound up building the replacement electronics packages for
the Shanghai mikes... the original electronics weren't worth modifying
because everything about them was lousy. The only solution was to scrap
them all and start new.

I'm not saying you can't conclude somethings not worth modifying after
taking it apart / looking at schematics. But if the way a compressor sounds
to you after using it a few hours doesn't turn your crank is it ignorant to
assume (as nap seems to have) that it's not worth modifying?

Well, why do you want to modify something? That's the first question.

Wow, it's amazing how fired up you guys can get over a POS compressor.
Well, the auction ending and I got $50 for the thing. Not too shabby.

Dunno what's happened to my usual news server today. Sorry for the
Googlepost

Mostly, you modify something that's already useful to make it better,
or make it so that it can be used with different gear. But every now
and then a manufacturer will come up with a product in a nice package
that doesn't sound very good, and someone will take up the challange to
turn the nice looking box into something useful. Kind of like your
SM-58 case with the B&K capsule in it.

Heh. Do you have an AKG C1000S you want to be rid of? ;-)

Not at all shabby.

Cos he has a box, ostensibly a compressor/gate, that has a nice functional
front panel with all the knobs and lights you would be likely to want. Now,
if the sound lived up to the potential functionality of the controls that
would be great, but it does. However it could be an interesting educational
and hobby excersize to make it usable at relatively minor financial outlay.

Could be a Recording article in there Scott !

Hi, Andy - We've gotta start bugging the Black Lion guy. I never heard
back from him when I wrote him a couple of weeks ago asking what was
up.

my name wrote:

So what's the big deal about modding something? We do it to everything -
cars for example. Sure you can go "off the shelf", but so can everyone
else. We do it because we want something with a unique style and because
we're naturally curious and creative. The Idea to take a reasonable-
featured device and replacing inferior components with better ones makes
sense to me. And fun, if you actually like and know how to do that sort of
stuff.


The trick is to find the right combination of modification complexity
and modifyer skill level so that it's worth while to work out a
modification to the extent that it can be published and promulgated (in
this case, sold as a kit). When an individual works over a piece of
gear, he can stop whenever he's satisfied that he's reached his goal
(or give up when he decides he'll never get there). But if you're going
to sell a mod kit you have to provide reasonable instructions for a
reasonable buyer. Given that most 3630s were sold to people who were
beginners in recording, it's not unreasonable to expect that they
aren't experienced electronic technicians, but I'm sure that a few of
them are.

When I saw that Ampex MX-10 mixers were going for outrageous prices as
"tube mic preamps" I dug mine out, gave it a listen, and a shrug. When
I asked what people thought was so great about them, I got answers that
essentially involved rebuilding the mixer - replacing all the
capacitors, replacing all the carbon resistors with metal film, some
even replaced the tube sockets with ceramic based ones, of course
replacing the tubes (the recommended brands varied, of course,
encompassing just about everything), sometimes even replacing the
transformers (but more often not, and this is probably the worst
sounding component in the whole mixer). Needless to say, mine is back
on the shelf, but no, it's not for sale.

I'm just sorry the one I sent you was some sort of oddball version, cause
otherwise we might have had some sort of serious evaluation (from you) by
now, rather than speculation.


Well, maybe one of these days we'll know what it sounds like.
