New Tubes = bad tone...

[glpg80]

Well, as I said above, the tube bias measurements are acattered all over the place, but raising the current has helped the tone. I think I had it way too cold. I think I may actually like these tubes a bit now. Next I'll have to get a quad that are actually matched.

Cool!! At that PV you were so cold it was no wondor your highs and lows sucked. Vinatge Genelex would have sounded like crap at that bias. 63% is usually my favorite in most heads I have had. Some like a little bit colder but not much.

i recommend 56% if you are experiencing "chewy" lows and feeling at 63% PD for any 6L6 type. bias them warmer for low volume playing, and a bit colder for high volume playing.

your response will improve, tube life will improve, and so will your cleans.

biasing can affect tone in alot of ways. this has been mine as well as other well known tech's experiences that i know.

56 is cool also. We're only talking 2 ma or so difference.

depends on the PV and also the bias circuit filtering. some will notice it more than others. the tube QC is worth mentioning as well

Tubestore.com sucks...

I am totally ashamed they are Canadian... I have heard nothing but BAD from
people who have dealt with them...

period.

I also like the JJ6L6GC, not expensive, but great, big tone.

Sorry to but in, but people often complain about the JJ's sounding very bass heavy and muffled, I have them in my 5150 II which is a very bright and upper mid heavy amp so it balances out but I don't think the OP would appreciate them based on his thoughts on the Sovteks.

Personally I dig them, wouldn't recommend them though. What amp are you running them in?

lol! Tubestore.com is not winning a return purchase. The tubes range in bias from 38.4mA to 32.1mA across the four power tubes. So much for the "perfect pair."

5-6 mA difference between 4 tubes is not that bad IMHO. A lot of people say that the tone is better with mis-matched power tubes.

I think it is a little better because of the crossover adding to harmonics. I just worry about the tranformer, especially in my older amp. Little less stress with matched. But you can take a quad matched 6, even 7 ma apart and match them into two pairs that are only 3 to 3.5 ma apart. The OT only sees two pairs,not four tubes. I know allot of players know this, but I come across quite a few that see four tubes, not two pairs in a 100 watt.

I run Ruby EL34BHT's in my TriAmp MK II and it OWNS...

SED's

Cornford Mk50H, not sounding dark at all.

I have the Winged C 6L6 in my MK50. I tried quite a few other tubes including NOS.

Ah, I haven't played one but it's a fairly bright amp, isn't it? I think the 5150 suits them well because it's a bright amp.

i run sovtek 6L6WXT's currently and love them. excellent bass response and a nice sweet but clear top end.

how do you have them biased? it may just be the wrong type of tube for your amplifier if your amplifier is voiced dark. winged C's are great but i prefer the sovteks - built like a shit brickhouse. never had a problem with one.

They're loaded in my TriAmp. Usually, I have to turn the bass up and the treble adown to get a balanced tone. I've got them biased at 30mA. I can only get them down to 27mA through the bias adjustment right now.

Somebody told me I could put 6l6gc in my Triamp it has el34 in right now its a MKII is that true..
It doesnt say anything about that but he says when he sells them people ask him to and he puts jjs in???

No. The Mark II is EL34 based. You would have to change the screen grid resistors to allow you to run 6L6s.

Sovtek WXT+ power tubes sound great IMO. The WXT is pretty meh tonally but durable.

I have a set of them in my Tverb. I love em. Havent tried them in anything else yet. I usually use SED or JJ

Thats what I thought and he told me I was wrong and said if you bias correctly you will be fine but Im not fukin up a 3000 dollar amp to get a little diff tone lol..I gotta ditch the TAD relabeled JJs in the pre though...Noisy fuckers..
