"battery died once"
100AH battery will fix that problem

Leaving the battery on the charger does.

Will a 6N6P work in the Dodd Buffer? http://lampizator.eu/UPGRADE/upgrade%20noval%20tubes%20to%206H6P.html

Yes, It will, but 6H30DR sound a lot better.

Agree, the 6H30DR takes the Dodd up a notch for sure.

Does anyone know what the output impedance is of the 6H30DR?

I can let you borrow 6H30DR to try.
Let me know.

The output impedance should be lower than the 6922 tube with the 6H30P-DR.

The 6922 was around 56 ohms output impedance.

Could the basic buffer be upgraded to the original buffer down the line?

Yes, basic kit 1 input and 1 put can.

How much play time are you guys getting out of your batteries and is there a battery in particular you recommend? I was told I could use two in series to double my time, but I'm not sure how that would work... would it take twice as long to charge?

Any info is appreciated.

Buy the ctek smart charger and stop worrying about battery run time! You can leave the charger connected at all times.

Agreed. Originally I was running off a 32 AH SLA battery (or 26, I don't remember for sure) After a few hours of listening, the battery would barely drop. I have a CTEK and was never able to hear it, so I ended up leaving it on.

Now I run the Buffer, a Class D amp, an Alix PC server and a V-link USB to SPDIF off the same Kinetik HCA1400 battery with a CTEK always attached. I have not had ANY problems when listening up to 6 hours at a time...

It does have the CTEK. I'm borrowing (and likely buying) this unit from Trung. I borrowed it a month or so ago and remember it died on me twice mid listening session in the week I had it. One time I wasn't sure the Ctek was setup right but the other I think was...

If I can get a full day's use out of it, that is plenty. It will just charge over night... otherwise I'd like to add another battery to the mix. I'm in a house with a todler where I don't get much time to listen and kind of turn on my stereo when I get home and take my 30 minutes here and there when I can until bedtime.

Make sure the CTek charger set mode to snowflake icon (AGM battery)

morganc · « **Reply #1055 on:** 23 Sep 2011, 08:47 pm »

I played mine for three days once and it never came close to dying with the Ctek charger on the entire time. I think my battery is the same size as Trung's btw......

Ok how do I order one? Can I add plat bypass caps? What tube should i get and where the DR is outa my price range for now.

TrungT · « **Reply #1057 on:** 24 Sep 2011, 10:56 pm »

You can start with 6N1P
see your Pm

just put up a Ctek U800 for sale, more recommended for 14ah batterys, will charge agm's

Vinnie Rossi, Red Wine Audio, runs everything on batteries. He's a super nice and helpful guy. I know he wouldn't mind sharing advice regarding SLA's or whatever and the best options for charging.

Just a thought...
