Tufnel JRC386D IC

[Rockitdog]

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?

National - LM386N

Thanks

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.

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

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."

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 .

Classic Tufnel.

Thanks a whole bunch everyone. Loads of options. Appreciated.



Rock on!

Very handy to know.

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.

Hi,

Ist it possible to replace the JRC386D IC with a Tube ? 

Thanks in advance

[JustinFun]

You could replace it with a tube *amp*
