Congrats on the BHC. I found the speedball upgrade to be a pretty clear improvement as well. GEC 6080 in the power slot? I recommend the mullard cv4003 for the input tube. Of the few 12au7s I rolled I liked that one the best.

It's a GE that came with it. LOL.

I took the photo as soon as I installed it.

But I quickly kicked it out of the amplifier.

I am and it does a much better job as a pre-amp than a headphone amp in fact. Important is to set the volume a bit less than 1/4 all the time. A better and warmer dedicated pre-amp would be a Yaqin SD-CD3 driven by dual 6SN7 (Raytheon in my setup - @bcowen loved ones).

Thanks for the tip.

I don't intend to sell Darkvoice, but it will probably work as a preamp.

It will but you will be looping inside the volume circuit of the DV.

I didn't understand what you meant.

My native language is Portuguese.

Could you explain it to me in other words?

I think I'm the only one in Brazil that has a Crack. LOL

OMG! How does everyone else go, um, #2?

What I mean is normally with a classic pre-amp setup, the same audio signal should go in and pass through the audio circuit (tubes in the DV case) and again go out without passing through the volume circuit so the volume is controlled by the audio original audio source and not the DV.
In the DV case, there is no way to avoid it passing through the DV volume circuit adding a 2nd volume circuit in the path.

@bcowen still refers to pee-pee as 'número um' and poo-poo as 'número dois'. How quaint.

I too had a GE as my stock tube. It was relabeled as a Dumont. It wasn’t until I learned about the bcowen dots of quality that I realized it was a GE.
I also managed to acquire bcowens second favorite the Phillips ECG in my first tube acquisition. Came in the “bag of 12au7” that I bought with a Mullard 6080 I found in a Craigslist add.

You are so lucky going 2 for 2 in your first tube outings. Remind me never to stand by you in a lightning storm.....

The Philips ECG 12AU7 is only slightly less horrid than the 5814 (which is supposed to be a higher spec 12AU7). Now don't anybody fall out of their chair when I say this, but I have yet to hear any GE as awful as either of those two,

Very Nice!

Going on 14 years since I started this thread. Glad to see it still getting some love. I'm not active anymore on HF. I sold most of my amps. But kept the DV336SE and all my adapters and many tubes.

Last time I was here, someone told me that dual triodes were sooo 90s and outdated. lol

Dual triodes will always have a place and always going back to them is fun. Right now a modest RCA 6080 & RCA 5692 rocking some Beyers. Nope, dual triodes are not dead nor will they ever be.

UT, if you are still on here, much love brother!

@UntilThen stopped by a few weeks ago. He's definitely still around giving sage advice!

Save for a very select few 6SN7s, Dual Triodes are definitely the way to go on (but not limited to) the DV!

Thanks HF and HF can mean Head-Fi, HiFi or HeatFan.

I am using dual triodes. See the front brown base driver tube in the picture? It's a Tung Sol 6SU7gty.
