I hope Gary has a full and speedy recovery....

I am building an enclosure for my battery power supply and would like to find an analog voltmeter.

Has anyone used one or seen one that would work fo me??

You could look for companies that sell solar electric equipment, there are several companies that make them, in 12 and 24 volt ranges.

Another possibility is from Auto Parts places. They have battery gauges that should be great.

Just a thought.

I have been looking at the automotive stuff and panel mounts from the auction sites but I was looking for something with a little more "character" befitting the Dodd Buffer

On another note I just ordered a 6H30-DR from parts connexion for $79
The tubes they have in stock are 1986 vintage as per an e-mail I received from Chris Johnson.

Very nice.

6H30DR with 86 date code, $79 = great deal.

I just looked up their site and couldn't find the 6H30-DR. I might like to compare the older vs newer. I just got one in from Russia marked 0902. Does anyone know if that is Sept of 2002 or Feb. of 2009?

09 is the year
02 is the month (not too sure)

Trung, the link doesn't work for me. Are you sure it is correct?

... never mind, I found it.

Can someone who has moved up the line from the Sovtek 6h30 to the DR's please let me know what audible differences they appreciated and if it was worth the extra cost of the tube? Thank you,
David

praedet, is that an automotive meter? It looks great.
I know that the digital meters would be more accurate, but it's more the look that I'm going for...

I've had the 6H30-DR tube for about a week and am really enjoying the added bass and detail (compared to the standard 12AX7). Trung keeps telling me the sound becomes truly magical once the caps settle in after a few hundred hours. Can't wait!

Yes, it is worth every pennies.

On my system (and YMMV) I've noted more bass and additional detail on instrumentals.

The pennies are adding up quickly!

But well worth it.
I should have gone with the DR tube directly instead of spending on the Sovtek as an intermediate solution.

Well.... I tried a lot more tube to get at this point 6H30DR.

But ... we all have Skeptical mind.

I think it is automotive/marine, and I agree on the accuracy, but I too wanted looks! It lights up with a nice yello glow

I agree the look is right on and accuracy is close enough to see battery condition
I think it looks great

Trung,
Did you compare the www.tubes.ru 6H30PDR for $40 to the PartsConnexion version for $79? The one from Russia looks to have an older date code, but not sure if I am finding the correct code. Have about 40 hours on the Tubes.ru version so far.

I know the new 6H30PDR sounds better to me than the Sovtek or Cryoset Sovtek 6H30Pi. Just trying to see if the PC one is a step up from the Tubes.ru version.
