Separate names with a comma.
That does not apply to vacuum tubes...only halogen light bulbs.
Do you own all of those?
Open back is what i prefer for drumming. It allows me to hear if I'm playing in perfect time...i have tried closed back in the past and i found that
Rolling a recently delivered Sylvania tall bottle "6SN7GTA" ($6 from ebay) (I think it is actually a yellow lettered 6SN7GTB tall bottle) + RCA 6AS7G. I think I like my Sylvania VT-231's and early '50s 6SN7GTAs better. Oh yeah, I also think I prefer to listen to my HD6XX's through the Darkvoice rather than through the THX AAA 789 (balanced or SE).
I think the owner of those is brownstd, as he posted some other tube combos in another post in this thread.
It shouldn't. But I have experienced this issue with my cell phone being too close to the amp. I'm talking like 12" away from the amp. When a text came through or a phone call some tubes would pick up on this and make noise. Some tubes wouldn't.
Also I might point out that if your DV is not isolated properly some noise can be introduced into the output of the amp. For example while using my LA Figaro 339 if I tapped the desk it rested on I would hear the tapping through my headphones. I solved this issue by using an amp stand and vibropads.
Lol... First sentence of that post reads...Not My Tubes... I just have the consumer version of the RCA Grey Glass pictured there, same sound just not as robust of a build.
Thinking of selling my Shuguang CV181-Z (Black Treasure) In near MINT condition, PM me with offer.
Actually it only recently went away, I had it running non stop for 48 hours and still nothing, and then another week or so of 10 hours per use daily. only now it's barely noticeable but I can still hear it.
Gonna do the 220uF cap mod regardless.
I can still hear it.
Sorry...my bad..lol, i'm an idiot!!!
Wow the DarkVoice is sensitive to noise, traced an electrical noise issue to the power brick I was using for my notebook source. Switched to another PS and the noise was gone. Never heard the noise before on any of my other amps. But then again never heard such clear detail in the upper frequencies before either, even with the stock power tube.
Any tubed amp is betterment off its own non shared power source. And be prepared to collect some tubes....lot of fun.
I've got a small collection from the 2 other amps and preamp I had before the DV. My wife is none too happy about the prospect of yet more tubes. Do you know if the Massdrop DV 336 SE is direct wired or PCB?
Lol.. know what you mean...I get the eagle eyes everytime I'm surfing eBay and had no clue what pcb was until a quick Google just now.. so don't know, sounds like hand wired amps are expensive.
I know the DV used to be direct wired from reading up on the fitz mod (used to cure the hum problem with some 6sn7s) curious if the latest versions still are. I guess I'll wait until the warranty period is over before opening it up.
