What value Sonicap Platinums are everyone using for the bypass on the output caps? I already have a pair of 0.1uF/400VDC Platinums from another project that I can use.

Once I have one of Gary's Battery Buffers built, will see about having a small GTG. My room does not have much room for seating. It will be running the Super-V's with Gary's Battery PA.

Another fun thing with the battery buffer will be the tube trials.

Have the stock 6N1P coming with the kit, a Valvo 7308, Siemens CCa, a JJ E88CC and Dario Miniwatt 7308 to listen to. Much easier when you are only using one tube!

The two 12VDC/75AH AGM batteries are charged and ready to rock (one for the preamp and one for the PA is overkill, but I already have them). Just need the buffer kit!

Will get the Sonicap Platinum 0.01uF/400VDC bypass caps as well. Doing the mod while it is being built will be easier.

I picked up my kit at the LSAF this weekend.

As soon as I get a new computer built (mine died by lightning while in Dallas

) , I'll post pics of the build.

I bought one of these http://www.amazon.com/gp/product/B002MT8S7E/ref=oss_product
for my battery. It flashes a green light when charged and yellow when down to 12.6V and red when down to ........ well I don't know yet but I will find out. Yes I know you can just leave the charger going all the time but I have this thing about unhooking it while listening, I'm just strange like that.

Scott,
Gary told me he had a kit for me at LSAF.

This was me when I did not come:

Oh well. The purpleheart faceplate and remote should match the PA nicely

Well since you had results, anyone here in Austin pickup a buffer?

etcarroll · « **Reply #451 on:** 18 May 2010, 05:28 pm »

Sounds like a plan - I'm in Oxford, Southern Chester County, 15 mins from the last rt95 ramp in MD going north.

Hey anybody else finish their kits yet? Let us hear from you!

I've started mine, but I am going to wait on photos until I get my computer back from the shop- this %#@*&% ancient laptop freezes about every third line! But so far, so good.
btw, Gary you have a PM.

HAL · « **Reply #454 on:** 22 May 2010, 02:58 am »

The kit should be on the way! Got all the batteries charged and waiting.

I just wish it were here! I need to smell some solder rosin!

Thanks to Gary for his assistance with trouble shooting my kit.
Kit should arrive shortly from check up.
Apparently the problem was with 6V/12V power-toggle switch.

While looking at some wood stock leftovers, I found this cute piece of mineral stained poplar and made some quick enclosures for pre-section & battery power supply. To finish it off, I have cut and pre-drill 1/4" aluminium plate which will be used for top cover.

Gary's maple knobs arrived in perfect condition. A real eye candy.
I have modified them a bit by inserting oversized, darker inlays for contrast and pure fun factor.

Hopefully soon, I'll be able to share my initial impressions of Dodd Audio kit.

Till then......

All right Gary, I finished it last night after my mishap

Here are the pics of the build and finished product. I also made some DIY silver cables.

For now it is hooked up w/ a modded SACD player, through an Outlaw 7700 to some Ninja modded Polk LSi9s.

It will be in a 2-channel DIY set-up soon.

It sounds amazing. The biggest change was the 3-dimensionality the soundstage now possesses. And that is with 20 minutes of burn-in

I know my wiring is messy, but this is my first build, so give me a break

Sorry for the HUGE pictures!
