Topic: Tascam DR-70D 4-channel audio recorder (Part 2)

The Lowepro Nova 5 fits all my gear nicely.  Love this bag.

Oh...by the way, I meant to mention this earlier but in a recent email exchange with Tom Duffy at Tascam he let me know that there is no MKII version of the DR-70D...FWIW

Apparently they just can't decide which colour to use for the handles for that model, so they've shelved it for the time being...

Where did you get those cool yellow covers for your XLRs?

Mine came with the cables years ago from The Great Gumbino here on TS.com.  I think you can get them from Mouser Electronics though?

[Life In Rewind]

Red and green capacitors are soldered in. Nothing was desoldered there. They (both red and green) are Wima MKP-2 .01uf/250v 5% poly caps that give better top end detail around 20khz. The second pic just shows the LME op amps soldered in place (2 are visible, one is under copper shield.  Those replaced the NJM4580s. The flip side of PCB also had the NE5532s replaced (no pic of that one though), forgot to take one and am not taking apart again now that everything is put back together.

Hopefully this helps if anyone else attempts it.

As far as specifics, the copper shield is placed loosely in there. Extra tape was applied to keep in place to avoid shorting out anything. Unit is somewhat difficult to get everything disassembled. Very tight components make for difficult soldering workspace.  Complete mod uses 5 op amps and 8 poly caps. It reworks both input and output stages. I think that's it.

Since the Jim Williams commentary only inspired this mod (sounds like you swapped a different set of op-amps) - shouldn't this be dubbed the "Cheese-mod"

I had extensive communication with Jim Williams through this process. He initially modded his unit and only did the 3 chips and capacitors. All I did was make him aware of the additional two NE5532 chips on the flip side of the PCB. Once he was aware of those he modded them as well on his deck. Only after he did the complete mod, and let me know it further improved the sound, did I get the detailed instruction from him so I could mod my unit.  Definitely a JWmod...not a cheese mod.  I wish I could take credit for it but I am a newb when it come to electronics.

I did record some of my church worship band this morning and to my ears there is definitely a clarity and detail to the recordings that's seems more pronounced to these ears. It wasn't the best representation though since I was not in the best location and the system lacks a lot of low end. Next time out with the deck will likely be this weekend where I can get a proper recording made.

Thanks for that link!  The shipping is more than the item though, so I'll look around to see if other sellers have them.

And change the handles to which cheese color?    

[F.O.Bean]

Yea I was thinking that too. Tascam always changes their mkii models to the red handles, and the 70D already have red handles, so I kinda thought JW was mistaken

Blue cheese mod with iridescent blue handles  Ha! I think JWmod will suffice tho

The Strut bag came in today. It's not going to work unfortunately. Not a great design. The 70D fits perfectly inside the bag, but getting to the inputs are very difficult. To get to the 4th XLR input, you would essentially have to take the recorder out of the bag.

Well that's a shitty design. Id just keep it in a bigger bag so that you can easily get to the inputs/outputs

[leehookem]

Yep.  Looks like my RM-Multi, that I already had, would have to be it for now.  Just need a couple of slight mods to make it work.  Need some perfectly cut, super dense foam for under the recorder.

That's where I purchased Dummy Plugs for Female XLR Receptacles.  Shipping is a bit steep if you are only getting one item, but if you can make your order large enough with other product, it will offset that cost.
