Wow excellent job indeed on the HA-5002!  Thanks for sharing the impression of HA-5002!
Just wondering, why you choose the SOIC-8 type for the HA-5002 and not the DIP-8 ?

 
The quick answer is, well, HA-5002 doesn't have DIP8 version. It is either SOIC, PLCC or metal can. Even if there was an DIP8 version, the pins out aren't compatible with regular buffer anyway so it still won't fit the E12DIY. SOIC with the special BrownDog adapter is the only way to go.

Well, i have around 8 or 9 HA-5002 in DIP-8 version
It does come in DIP-8 version, Farnell has it.
If you search PPA Project by Tangent and team, they used the DIP-8 version of HA-5002.

I believe the DIP8 version has been discontinued awhile back (Intersil no longer lists it as active part), though there might still be some NOS around. Still, as I save said, the pin out is different from all the common buffer we used in E12DIY and therefore you can't use it directly. Even with an adapter, the height of DIP8 + adapter will exceed the E12DIY casing. In short, it just impossible to use the DIP8 version of HA-5002 on the E12DIY. The only way around is to custom make your own adapter and mount it upsidedown like the stock BUF634 included with E12DIY, but that is really a lot of work when SOIC + adapter is readily available.

Xin made some nice adapters that had thicker traces but of course, his are no longer available but they are lower profile and would have worked.

Just recall that HiFlight does included pre-mounted SOIC HA-5002 on adapter with his topkit. Those of you who are interested can probably get it from him, though do confirm with him about the height first.

Yes, you're right, pins are different.  So SOIC-8 + adapter is the only way.

I was hoping to buy one of these but i had a few questions first...
I'm a beginner at circuitry and am a first year student studying EEE...
Do I need any soldering skill to use just the given buffers and op-amps???
Did anyone find any good setup for the momentum, hd518 or xba-3 yet???

 

[Loquah]

No need for soldering skills. You'd only need to solder if you decide to use other chips not provided with the DIY.

As for setups, I think the general consensus is that the LME46900 + OPA1611 combo is nice, but that's from memory so others might correct me. Either way, all setups I've tried sound good and it's fun to switch it around to find what you like.

 

[jamato8]

I will have one in a day or three. Look forward to the possibilities.

Wondering if you guys notice that the E12DIY won't automatically cut off charging once the battery is full?  When I left the unit charging over night, the red light is still on in the morning.
 
Or is it a faulty unit I received?

when the red light become stable...it mean it's fully charged..

 

[alflying]

thanks

 didn't realize the red light was blinking while charging

 

[CosmicHolyGhost]

yeah, it  will automatically turn off charging if I recall... when it is charging, the red light fades in and out..

 

[alflying]

on a side note, I'm happy with the LME46900 + LM4562 combo.  recommended for those who likes a smooth signature with a slight hint of bass boost

No, it is completely normal. The red LED flashes when charging. Once the charging is completed, it will stop flashing and stays on. Don't worry as it does have over-charge and over-discharge protection built-in.

On a unrelated note, Just received email that my akizukidenshi.com's JRC order has been shipped out by EMS Japan. Hopefully will see it in a week.
