Looking for tube recommendations when I retube my amp...I've heard from people that the chinese ruby tubes sound really good but reliability is an issue, jj tubes are generally very reliable but have a darker tone most people don't like, and tubes like the tung-sol reissues sound good and last a long time but are more expensive. I'm looking for a good balance between tone, reliability, and price. Both preamp and power amp.

I've had a few sets of JJ's, but haven't noticed them to be dark at all.

JJ's made my (already dark) Roadster darker. My 6505 has Ruby's in it and I think it sounds ace. :yesway:

i hear tons of jj reliability issues

i'v always gone with groove tubes. i know they are rebranded, but they are guerenteed for 6 months i believe and you can get them anywhere pretty much.

I'v tryed sovtek pres and thought they were horrible. but the pair of 6l6's i just got were groove tubes but i see they are rebranded sovteks because it still says sovtek on the back:lol:

But i'm not noticing any differance as far as the sovtek power tubes.

From what i'v read, rubys are rebranded aswell

I'm actually in the market for some pre's and i'm thinking of electro harmonix.
Also, from what i'v read, some people never change their pre's and notice no difference.

I would go with a tung sol 12ax7 in the v1 position

then JJ ecc83s in everything other than the PI where i would put a Jan Phillips 5751

then a set of =C= in the power amp

total tonal bliss and utterly reliable

for cost reasons you may want to replace the =c= with something else but it wont sound quite as awesome

i've heard reliability horror stories with JJ's too, all I know is when my 6505 had ruby's in it originally they kept frying...of course that could have had something to do with me mod'ing the amp and I may have done it incorrectly at the time :lol: plus I remember reading somewhere mesa used to use ruby but switched to jj because of reliability issues, so I really have no idea what to do. :lol:

Never had any problem with JJs. But, I've pretty much only used their 12AX7s and EL84s.

I have been unhappy with every set of JJ power tubes I have ever played through.

If you're going to buy rebranded tubes, buy Mesa. They're Ruby tubes, but since Mesa has first crack at everything Ruby imports, you're getting the cherry picked tubes that pass Mesa's ridiculously stringent testing process.

I really liked the JJ's I put in my Nomad, against the stock Mesa tubes, but those tubes might have been really, really worn out :shrug:

Groove Tubes are good, too. Had good luck with both brands.

I liked them in my XXX. Whatever it is they had - it was what I needed.

Every single JJ tube I had went bad within a short time. The longest lasting pair I had lasted 3 months. the shortest 3 days.

I've heard that going with 6550 power tubes is the best for metal it tightens up the bass and gets rid of the shrill noise. I've also heard just go with whatever it came with stock and putting brand new tubes of the same type that came with the amp could be your best bet, think about that for a minute and use a little common sense what else do you have to go by unless you have an amp guru living in your backyard!
