I swapped out my HD6XX worn pads with brand new Dekoni Sheepskin Pads and immediately noticed a drop in the mid highs that seemed to elevate the bass a bit, liked the bass boost but missed some of the crispiness.. until I remembered I'm a tube roller I gots a special tube that has screaming good highs! Enter the Electro-Harmonix 6SN7EH I am now one with earth again.. (and I still have the bass!)

Hey JKDJedi...it looks like your ElectroHarmonix 6SN7EH is the new one (reissue) right? Did this tube require burn in on your DV....was there any initial hum issues with this?

I honestly don't remember. RCA Grey Glass is a better tube IMO.

Cool Thanks. Another tube to put on the bucket list to try...Yeah, I was only asking because i'm 2 for 2 for hum on new reissue tubes. This thing loves only the stock and any NOS i throw at it which I have had zero hum on any of those. Lol. Not that its a bad thing...

And with all that my NOS tube I just got in has the hum...LMAO... well the positive note on NOS tubes with hum is that you know your popping its cherry! Burn in time for my spanking brand new Westinghouse 1957 D getter 6SN7GTB (left), I'm told it's miles ahead of the 60's halo getter version (right) so really anxious here, (oddly the 60's version had no hum when I got it) So we'll see.. ..

Thanks, I'll give that a try, and have read that Detoxit might be ok to use... thoughts?

Use it....It works Great....but...be sure to use the spray and not the brush-on crap. The crap just will NOT dry.

You won't regret it, great tube, gets better with burn in, and I mean better.

The 7236 just arrived this morning and already loving it. Nice bass slam more detail in the mids, highs are etched in. Also more gain. Will report more as the tube burns in.

Yup.. I have stocked up on Tung-Sol 7236s.... I love the way the Tung-Sol 7236 works with various 6SN7s. I listen mostly to rock, EDM and punk music, so it takes a fairly fast responding tube and one with really good bass to make my music sound right. The Tung-Sol 7236 paired with the Philips is to my ears, the absolute perfect combination of speed, impactful but tight and deep bass, soundstage and a great midrange and sweet but crisp high end.

The Tung-Sol 7236 pairs incredibly well with

1. The Philips JAN 6SN7WGTA
2. The Sylvania 6SN7W
3. The Ken-Rad JAN-CKR-6SN7GT

After a monumental amount of listening, those are my top 3 combinations to use with the Tung_sol 7236.

Cheers, and happy rolling!

Boy, the DarkVoice is fussy about it's 6sn7s. A new production Tung-Sol 6SN7GTB hums, one vintage TS mouse ears has a noisy right channel, another branded Motorola has a low level hum. Finally found one the DV likes, a vintage TS mouse ears branded as a Raytheon. The ones the DV didn't like are slated for the Schiit Vali 2 which doesn't seem to care but then again doesn't quite come up to the DV.

This from Ripper2860

"The DVs are very highly regarded, but there was a an issue w/ DV336 (including SE's) that exhibited hum due to a design or build flaw. DV336 uses AC (Alternating Current) heater circuits as opposed to DC (Direct Current). With AC, the 2 heater wires going from the transformer to the tube heater pins should be twisted for shielding purposes to prevent hum. Quite a few DV 336SEs did NOT have a twisted pair of wires but instead were straight and side-by-side. This creates a real problem with hum and varies in intensity from tube to tube".

Ripper2860 helped me pick out my last tube (which is phenomenal) had some hum, but with 12 hours of burn in went away COMPLETELY.

Yes. My favorite c-top 5998 has a pair of bottom getters.

I don't have Syl 7236. So please don't blame me if they are not good....

Thanks for the explanation. Two things then, 1. I'll put the humming tube back in and give it the appropriate burn in time and 2. When the warranty period is up open the box to check the heater wiring.
