according to Jerry @ FJA mods, has gone to crap. he said he no longer recommends or installs any tubes from these companies. im glad i talked to him before i purchased the high gain jj tube set from eurotubes. he recommends Tube Amp Dr power tubes and Mullard, TAD, or Ruby in the preamp. my stock 6505 has all ruby tubes. anybody have any recommendations for my amp? i know a lot of people like to run different tubes for pi and mix up the preamp tubes. i like tight and chunky with a lot of meat without getting muddy.

I've had problems with almost every (modern) tube company. I had a JJ ec83 pull apart when it was removed from my amp.

SED is the only company I have had no issues with, but I have only bought a few sets of tubes, so not like that is an indepth comparison.

But Ruby rebrands JJ, Sovtek and anything else they want to (they do not make tubes at all)

Almost all brands besides the Shuguang (or what ever it is) is owned by New Sensor. That is JJ, Tung Sol, Sovtek, Mullard, Svetlana, Genelex

Ive had issues with New Sensor stuff except their mullard ri 12ax7.

JJ are better off bought from eurotubes or ruby rebranded ones from someone else.

^^New Sensor doesnt own JJ

wonder if that high gain metal set eurotubes sells is worth it or makes a huge difference in tone. i was really interested in that kt88/sl6 combo they offer but... everybody tends to believe mixing kt88's with 6505's is a big no no without doing some serious mods

Ruby Tubes are JJs in a lot of cases.
If you buy from a good dealer, they're going to test the tubes before you get them. If you buy Rubys from that same dealer, all that means is that Ruby tested them, then sent them to the dealer, with some markup. If JJ is having QC problems, your dealer would much rather have Ruby take the hit on the bad tubes than doing it himself. That's a legitimate business decision, but he's only suggesting Ruby tubes because they're higher margin for him than JJ. It doesn't actually mean anything to the consumer beyond perhaps a higher price, and that value should be up to the consumer to decide.

So if you're buying tubes from Guitar Center, yeah, get the Rubys, then at least someone has tested them. But if you're buying from a dealer that tests their tubes, I wouldn't pay more for Ruby tubes just because the guy is whining about JJ's QC. It sucks that he's not making as much money on JJs, but I'm not going to buy some shitty rebranded Sovteks if JJs are still available, and I don't see any point in buying Rubys that have just gone through an extra middleman if other options are available.

I'm still going to buy JJs. It's too bad their QC is bad, but all that means is that I might pay a buck or two more for properly tested tubes. They're still the best new tubes on the market, and it's foolish to pay for untested tubes anyway. So, it's a bummer that the dealers aren't making as much money, but I don't base my tube choices on how much money someone else is going to make on them.

y'all have an awesome running game and your linebackers play with a lot of heart and soul. badgers are probably the classiest team the gamecocks have ever played. cant remember your super star linebackers name but he was awesome! he knock the crap out of shaw or davis then help them off the grass. very clasy guy. much respect for the badgers! to bad we found y'alls weak spots. your safeties sucked up the middle on seam routes and your offense wasnt as effective in the red zone. badgers are set for a fine future for atleast 3 years, again... much respect and a good ball game!

this doesn't really make much sense, mainly for the reasons Robb pointed out.

truth is i don't know of any tube company where the 'Quality Control' hasn't gone to crap. i don't know of a single modern brand that hasn't shipped dead tubes.

from what i understand mullard, TAD, and Ruby are just rebrands... of other companies that have a poor QC program.

They're made in the same factory on the same machines. The only difference is the grid. The plate, cathode and heaters are identical. Well, that's true of the 12AX7 anyway.

They are the highest gain tube being made right now

One of the tube stores did a gain comparison and the new Mullards had the highest gain rating of any current production 12ax7

wow. maybe their doing something different since New Sensor took over. i heard a modded jcm 800 2203 loaded with mullard 12ax7's and i wasnt impressed at all. the cleans were very good but the gain was on par with a stock jcm800. again, this was like 5 years ago.

you think the mullard's would have more balls than the jj's via preamp 6505?

I don't know.
I use a Mullard 12ax7 in V1 of my JCM2000 and JJ ec83 in V2/V3 and it sounds really nice

Afaik the Mullard reissues have always been made by New Sensor. Original Mullards were made in the UK by Phillips (and some in other countries like here - but none in Russia)
The old Phillips Mullards are so much better than the Russian ones that I think it is a travesty that they use the same name.

I thought they reworked the new Mullards a few years ago?

Could have just been worn out tubes, too.

I go through a lot of tubes and the only JJ that has been faulty was a 6CA7 with cracked glass - and that could have happened at any time between the factory and me.

^Their 6ca7 tubes are robust looking. Those with el34 amps are gonna like them for a big low end & low mids than the e34l tube.

As far as the high gain set from eurotubes is concerned, i dont see the need to get high gain 83s for a 6505 amp. The regular ones will do fine. Besides those 83s are mostly high gain or close to it anyway.

The mullard ri 12ax7 is a solid tube but pricier, sounds rather compressed as well to my ears. I like the jj ecc803s over it.

Get one regular ecc803s for the PI spot if ya gonna load jj 83s in rest of the spots. It will lively up the amp

i got 20 a few months ago, no duds. from (from MF though).

i still have 8 12at7's that are good that i haven't figured where to go.

i plan on picking some more JJ's up next time i ordered (although it may hit a little out of the budget for my amp).

Wait for a tubedepot sale. Get some 83's and a couple 803's along with some sovtek LPS and JAN5751.

They normally knock a $1 off during the sale for preamp. More $$ for power amp tubes. Good deals on EL34's if you have any amps that run them.

I have EL34L's in my Randall. They are the ones to go for for a big bottom end. The 6CA7's I would recommend for those who want ACDC type power amp crunch, I wouldn't rec them for getting more bass, that's an EL34L's job really.

The ECC803 is a great V1 tube. If you're gonna stick one anywhere, that's where I'd put it. It's also where it does the most good, noise floor speaking.

Yeah, but the EL34L does it without sacrificing midrange. I really haven't had much to do with KT77's tbh so I have a limited basis for comparison. You may very well be right. Those JJ EL34L's are a mighty tube though, nonetheless.

I have long plate JJs in V1 and V2 and couldn't be happier. throwing a JAN 5751 into the PI when I feel like buying tubes. Might try to pick up a 12ay7 and maybe something else while I'm at it.

If I ever win the lottery, were going to start producing tubes in the states again.

the only reason i got them from MF (which is because i like the small sites and shops) $9 after price match. that was really hard. now i wish i would have picked up 20 more. i have quite a few of half-life of just about everything and some nearly new.

i will have to give the LPS and 5751's a shot. thanks
