Who owns groove tubes

Also main reason you want Grove Tubes is the Power Tubes. If you want to go OEM for preamp, I do this too but for power tubes I always always always always always get Grove Tubes because they are the best quality and I dont want to mess up any of my amps and want the best sound!!!! You want a damn good high quality and tested power tube IME to get the best sound possible.

Grove Tubes provides this. Second they offer Silver and Gold Series for their Power tubes both undego the crazy test to weed out the crap that eventually get shiped back to Sovtek, Shuguang and JJ and sold to the plebes. Mainly you want the Gold for the power section as these are matched.

Now other companies claim to do this. Test and match and whatknot But really who knows Groove Tubes does it for damn sure. Fender owns them. Fender makes good stuff and is pretty high quality in genreral and has high standards. I trust Groove Tubes and Fender especially in for Power tubes. Yeah it cost a bit more but damn worth every penny You dont want to cheap out on these or second guese quality or testing of these.

Also plenty of nastalgia regarding vintage tubes Last edited: Jan 8, Jan 10, Age: 69 Posts: 9, Jan 11, Jan 12, You must log in or sign up to reply here. Show Ignored Content. Your name or email address: Do you already have an account?

I don't like them and have found a very noticable improvement in tone by changing them out for JJ's. Anyone else find the same? Thinking that if this happens frequently, Fender would have to consider why they're letting amps go out with unliked tubes?

Or perhaps I'm alone on this? Catoogie Senior Member. Messages 3, Only change tubes and speakers when they fail. Space Hammer Member. Messages I believe Groove Tubes don't manufacture most of their tubes - they are just rebranded Sovteks and a few other manufactures. I have a Fender Hot Rod Deluxe and haven't swapped em out. I like the tone i'm getting. Snap Member. Fender bought Groove tubes. I had a drawer full of them. Thats really not good because you are still overworking your power transformer.

Power transformers are sensitive to "magnetic saturation", an irreversable condition that prevents full output. Its obvious to the amp owner there is a problem, "it just doesent have the nuts it used to", but is very tricky to spot on the test bench.

So all you guys that think the tubes that came with the amp 10 years ago are fine; you don't know, you need to get them checked.

You are taking a huge risk. You own a vintage amp? Then you should know how important, expensive, and sometimes impossible to replace those transformers are. But getting your tubes checked and possibly getting you amp to sound better than new is fun - do it.

All output power tubes finals will eventually form a heater to cathode short. Output tubes should be checked for merit and h-k leaksevery six months. My store has one for you to use free of charge. Microphonic tubes have something loose inside them that, when gently tapped or otherwise vibrated like sound from your speakers will cause the tube to make its own sympathetic sound.

Just past marginal microphonic failure you will hear a grumble when you play a bass note. More microphonic tubes wont let you turn up the treble without tearing out a shriek. Worse still you can't play lead style distortion without your amp squawking at you. There are lots of shades of grey in this. If you are hearing any tones that don't belong then you most likely have a microphonic tube. It may plague you only under certain conditions.

But a bad tube is good opportunity to upgrade the sound of your amp. Other failure modes are:. Now wait a minute, you said you just put new tubes in right? And it sounded great for a while, but now yadda yadda yadda. Here's what happened. You heard from a friend or teacher that you need to put in Brand X tubes to get a good sound, because you were not completely happy with the sound you were getting. Then you went to the store and got those puppies.

Somehow you knew that there is a high failure rate in new tubes, and bypassed all mail-order possibilities. Now, you either made the mistake of putting them in yourself, or the technician you took it to biased your amp one of three of the four correct ways that won't work to keep your amp out of the shop. You didn't let some retail clerk put them in, right?

Again, the technician you took it to biased your amp one four correct ways, but not the one method that will work to keep your amp out of the shop. This happens all the time. I said there are 4 correct ways to bias an amp. One of them is better, so your amp is more likely to stay out of the shop. Unknowing or unscrupulous repair shops will make you a steady tube customer. Who's to blame? Maybe the tubes they are using, maybe the tech, maybe you had something really go south in your amp.

Either way, if your back for a third set of output tubes in a year! Go find a tech who knows what the good tubes are, who really makes them, and how to keep your amp out of the shop. Follow his recommendations, and pay a little extra for probably his good tubes because you will save money in the not too distant future.

Let your amp cool for 3 minutes, that means completely off, before you attempt to move it. This will help keep your tubes from shorting out. They are the same as light bulbs: a vacuum, a heater. And if you unscrew a light bulb while it's on it usually blows because of the violent shock taking place while the hot metal filament is transitioning from it's hot almost molten like state to it's cold, very hard and brittle state. You banged it when it was changing from hot and soft to cold and brittle.

Same as a tube. Call the amp manufacturer, and get the name of a factory authorized service center. If there isn't one, ask your friends if the shop they use does good work. A busy shop will not have the best turnaround times. A good shop will always be busy. In my area shops doing quality repairs have 4 to 8 weeks turn.

My shop is open 4 days a week. I charge a premium of twice the labor for emergencies. I also will go to the customer, but for a minimum charge. Will have to figure the table reference out as I go and how to order it on the page.

For now some random findings. Last edited: Aug 31, Blue Strat Member. Messages 30, Groove Tubes WAS having some custom tubes made for a while. Both were made in China and were exclusive products. Not sure if they're still doing this.

TAD Tube amp doctor does something similar, also in China. Apart from those, I think you're list is all inclusive. Blue Strat said:. TEPR Member. Messages 2, Great thread. Should be stickied. Seems like there is room in the first post for that info too. Maybe we could convince them to make guitar toobs. The Dirty Tube Member. Messages 1, TEPR said:.
