Tufnel JRC386D IC
« on: October 21, 2011, 05:50:36 AM »
Hi there

I am looking at Beavisaudio's Tufnel schematic and it lists 2X JRC386D IC's.



Just done a search on Smallbear and my Local supplier (Mantech) and nothing come's up.

Is this the same Amp?
If not, what alternatives could I try?

Yup , any 386N can do , JRC386D will be quite hard to find .

Recommend using a 386N3. Notes will fade more smoothly than with a 386N1.
Thank you, Joe Anthony. (The godfather of rock and roll.)


Anyone can drill a hole. But, if you want it off center or misaligned I'm your man!

Hmmm, I dunno, it's such a fine line between genius and stupidity, innit?  :icon_wink:

The 386D can handle higher output levels without letting the magic blue smoke out, and is JRC's all-purpose version of the 386.  NatSem's version comes in 386-1, 386-3, and 386-4 flavours.  If you're aiming for credible loudness through 8-ohm speakers, the 4 is what you want, whereas the 1's are for more modest headphone levels into 16, 32 (or higher) ohm impedance headphones.  The D will do ya for any of those.  More rugged chip, certainly, though I don't know that it is absolutely necessary for a pedal.  It may sound a little different though.  I'm sure "Beavis" tried out different ones and liked these.  You don't have to, though.

Smallbear has 'em:

"Japan Radio Corp. version of the 386 for "Smokey" amps."

http://www.smallbearelec.com/Detail.bok?no=207

JRC386D is now known as NJM386D

edit: mouser might even have the NJM386D, not sure. Look up the datasheet for NJM386D, you'll see it's from "New Japan Radio Co" or something.

He's not driving a 'phone , he's DRIVING A PEDAL !

It's like saying he's not driving a truck , he's driving a SCOOTER .
Though , i only have original JRC chips and none of natsemi's .

Understood.  Just clarifying the differences and what may or may not make them relevant to any given case.  This particular design wants a 386.  It doesn't need the ability to produce 1w into a speaker; it just needs to be a 386 of some sort.  Whether the JRC sounds better to your ears than the NatSem or some other form is up to you; same way it would be up to you whether a TL072 sounds better in your overdrive pedal than a TL082 or OP275 or CA3240 or JRC4558, etc.
