Babyface Mod For Avalon 737?

Has anyone heard of the Babyface Mod for the Avalon 737sp? The modification supposedly makes the attack on the 737 much faster. Has anyone modified theirs, and if so, what were the results? There's a guy here in NYC that will do for $70. Should I give it a shot or is it just a waiste of time?


Check it out!

Any chance this same mod will work with the VT-747sp comp also?

Not sure, but the guy who does it, his name is Steve. He's an authorized Avalon dealer and tech. I personally only know about the 737's
Here's a link to contact him for further info:

BabyFace mod

if you send the unit to Avalon Design, it's a charge of $80. Better let them deal with it since it runs for same price approx. They might re-callibrate your unit also - always a good thing heh

P.S. Avalon does not have an authorized repair man or shop anywhere in the world except for Europe distributor! I called them on this same issue and is what they told me.

Hey, i have been doing this mod for decades.. (in fact I am sure it began in Oz with the old purple knobs 737's). well thats what it seems. it s no big deal, just change one component on ther top compressor board, takes less than a minute.. we do em here, but supply a new board, so you can swap them out, personally i prefer the original times, as it affects the release as well, i am sure.

contact me for the details...

Hi Mixster,
I was going to get you guys to do mine, but I already had the component (all 50cents worth), so thought I'd have a go... found pictorial instructions on the net.. I really like it, definitely faster! It seems to have made the 737 a lot more useful for me.
Is Mr Taylor still working up there? Love to come for a visit sometime soon.

Best Regards,

Hi

What I know about Avalon gear you could write on a postage stamp in foot high letters (as in zilch) but something smells wrong with this mod.

If you reduce the value of the capacitor, you will not only speed up the attack time by halving it... you will also speed up the recovery by the same factor.

I would have thought that changing the series resistor to the 2uF capacitor would have speeded-up the attack without affecting the recovery... but that's just an observation... I don't have the diagram to confirm this.

This is the trade off with the mod and why not everyone foes it. I personally like the faster release time.

Hi

It's only that the 2c resistor could set the faster attack without other side effects.

I don't know what voltages the capacitor will see in the side chain, maybe 10 or 20, but there's nothing to be gained by fitting a 100 volt polarised capacitor into a much lower voltage environment.

I'd also suggest using a low leakage tantalum for the timing cap... it's what Neve did on the 2254, 32264, 33609, etc.

Mm, maybe you could try it... I don't know a lot about all that stuff, so I just did what the Avalon folks do anyway.
