Biaeothanata-Bassist Posted October 30, 2013 Share Posted October 30, 2013 I'm really interested in trying each of them out, especially the "Nitro" one in my Hartke LH500 to see what drive it can produce from the amp. Heck, if they're no good, they're no good! I'm not going to pass judgment on them until i've tried them. If they do suck, i'll stick a Groove tubes gold in it. Simple.

Biaeothanata-Bassist Posted October 30, 2013 Share Posted October 30, 2013 (edited) That's fine by me, the amps volume needs to kick in a bit earlier than it does to me anyway. I'm not on about getting valve distortion from it, just a bit more drive from the pre amp to make it a bit richer on the harmonic side. That's what I did with an old Trace Elliot I used to use. Regret ever selling it but this Hartke is a great amp Edited October 30, 2013 by Biaeothanata-Bassist Quote Link to comment Share on other sites More sharing options...

umph Posted October 30, 2013 Share Posted October 30, 2013 [quote name='vocrockguitars' timestamp='1382533866' post='2253285'] New pre amp tubes just released by rocket tubes. They come in 2 Variants. A low gain version labelled as CLEAN and a Higher Grade Version Labelled as NITROUS. We have put these in several amps and they sound very nice. Cryo Treated and other mod cons make these tubes an exciting new addition to the tube tone world. A great new Vacuum Tube. You can read info about them on [url="http://www.rocket-tubes.com"]www.rocket-tubes.com[/url] We are proud to be one of the first to get hold of these in the UK [attachment=146759:rocket-tubes-12ax7clean.jpg][attachment=146760:rocket-tubes-12ax7nitrous.jpg] [/quote] The website doesn't say a lot, there are no prices and i'd like to know what factory they came out of? I'm not a huge fan of the chinese cheapo 83's. Can't see the jacket doing a lot for microphonics. quite a few other websites offer matching services like this.

[/quote] "Unfortunately we are not at liberty to reveal our sources but what we can tell you is that the tubes that reach our distributors are of a small proportion of tubes that actually pass our criteria of testing. There are a lot of tubes that do not meet that criteria. We send the top tubes to be cryogenically treated and then re-test before final distribution. Currently we are only supplying to a handful of European and US distributors and do not deal with non Trade or public retail. Sorry about that. Unless you are a trade or tube retailer. If you are, we can discuss minimum quantity criteria and price breaks with you." So you can't find out where they're from and you can't buy them. I'd stick with Watford Valves, frankly...

Mr. Foxen Posted October 31, 2013 Share Posted October 31, 2013 That's some fudgy language that doesn't actually say the failed ones don't also go to be cryogenically treated, and be retested, before reaching distributors (presumably in blue jackets).

Bolo Posted October 31, 2013 Share Posted October 31, 2013 So how come nobody in w-europe is manufacturing übertübes? (Now there's a brand name!) There is obviously a demand.

throwoff Posted October 31, 2013 Share Posted October 31, 2013 (edited) The biggest tube makers used to be Russia because a bundle of Russian military systems still run with tubes, the MiG 25 still flys in active service and uses tubes! Since they began a hard modernisation process the demand for tubes dried up in the Russian military and so the factories closed. I would bet my bottom dollar there are military warehouses and storage yards in Russia with boxes of thousands of mint NOS 60's tubes sitting there doing nought...

VTypeV4 Posted October 31, 2013 Share Posted October 31, 2013 I've spotted 'em on ebay at £24.95 a pop..

I recently bought a quad of Shuguang EL84s for my Leak for the same monies. And inspite the stigma of 'Made in China', they're great sounding. These may well be from the same factory..

dan670844 Posted October 31, 2013 Share Posted October 31, 2013 These won't fit in any of my amps, as all my amp have valve cans for the preamp tubes. They look like shugangs to me by looking at the guts. I have tried their top end ECC83 via pm componets (golden dragon) they are actually quite nice. They are very warm, in fact too warm for me in my gear as its all valve and high voltage. But suspect they would be very good in a hybrid amp which you are looking for maximum warm. In my humble opinion there are two modern production valves that are good, that is the Gold Lions (russia) and the Full Music (china) Both have zero microphonics, balanced, smooth and very linear. The full music is the best it has a huge sound stage and a very low noise floor. Totally overkill for a bass amp but great in my stereo. I hear Rode have started putting them in their mics, they used to put telefunkens in..... But if you can find one to buy you are a better man than me, as they a produced in small quantities by a very old man in china! Quote Link to comment Share on other sites More sharing options...
