Looks like a few more people are getting tuned into the sound of tube overdrives...especially ones that use the valves in a proper circuit with the correct voltages...for a while it felt pretty lonely around here... .... |

I know. I don't know how I lived with out it! Beats any boss dist pedal I've ever owned, including my beloved HM-2s!
Only slight inconvienience is the fact its gotta run on its own power supply. But its fair enough since it runs on so many volts! She heats up a lot!.
I seriously can't stop playing this thing |

@ hateandwar, have you tried boosting it with your HM-2? I would've tried it but my bud wanted to try out my HM-2 I can't stop playing it myself, I feel I finally got that Fear Factory like tone I've been trying to replicate  |

Exactly my friend! I wish I'd have discovered these sooner, but at least I wont have to spend $4700 on a Diezel VH4 to get the sound I was contemplating |

In case you guys were wondering, or were interested?
The ECC83 is the European equivalent to the 12AX7.
Here is a quick cross reference for the most common 12A_7 series.
Going up in what you guys call gain.
There is also a 12AY7 not used very often.
All are interchangeable electrically & mechanically, other than for the gain.
European Tube Name EEC81 - USA Tube Name = (12AT7)
European Tube Name EEC82 - USA Tube Name = (12AU7)
European Tube Name ECC83 - USA Tube Name = (12AX7)

Never feel lonely bro' - there are more valves in my house than in a Mig jet fighter Reckon I could bring our local electricity sub-station down if I powered all the beasts up together - I couldn't be without them for gigging 
I'm so attached, that I've still got the first two valves that ever crapped out on me, from my 70's Fender Pro Reverb that started to emit smoke at a recording session - I chucked them in the tool box after the tech had fixed it (a knackered valve mounting too) and they've been there ever since!!! |

Nice list Doc, but there's also a tube with even more gain, the ECC803s that sounds really great for bass amps with a single tube or higain guitar amps. I don't know the 12A-- number for that. |

I've also read of people changing the 12ax7 and the equivlents for a 5751 tube after SRV made it famous in his amps...it's supposed to be a very clean sounding,extremely robust mil-spec tube...
I don't use the Blackstar but a SD twintube classic .. it uses a duet of premium, mil-spec, subminiature, USA-made Phillips-SylvaniaŽ 6021 dual triode tubes..AFAIK these were originally designed for NASA back it the heyday of valve and tube technology and are extremely robust and long lasting compared to other types of valves...it also uses the tubes in a HT circuit to drive them like a proper preamp section of a valve amp....
The_Doc ..i hear ya bro'...my little selmer 14 watt amp has nine valves in it on it's own including a rectifer valve.... in a 14 watt amp...!! plus i have the other amps plus a couple of old reel to reel machines with valves inside them as well.....
JC...i know what you mean as well about the Diezel amp...recently i was looking around with a view to changing my amp but i don't need a 'bell and whistles' all singing/dancing multi channel beast as i have the SD twintube as my preamp...getting a brand new single channel amp with the same build quality of my old amps is a rare as rocking horse shit... and when you do find one with the clean headroom needed for gigging like the DR Z stuff you would need to sell a kidney to afford one.......... |

I did that too, it really cleaned up the Normal channel on my Marshall jcm800 split channel without affecting the Boost channel too much.
Although the tube (in V1) is shared by both channels. |

The ECC803 is a high quality, low noise, long life 12AX7
Extracted from a web bost at the orange amps forum.
http://forum.orangeamps.com/viewtopic.php?f=2&t=20616&view=next
ECC803S = 12AX7 TELEFUNKEN WEST GERMANY
(Special Quality 50,000+ hour 12AX7),
arguably the best 12AX7 ever made,
very low noise and superb inner resolution;
this is the Holy Grail for 12AX7's.

Definetely yes to that.
I have put one from JJ electronics in my Ampeg BSP preamp and it made it come alive again.
That tube makes it sound so harmonically rich, it's amazing. |

Thanks for the conversion list Dr. Bob, I'm planning on switching out tubes in the blackstar distx in the future and seeing what other kinds of tone I can get out of it
I don't have it pictured yet, but I'm currently running this through my Marshall Mode Four head coupled with a Marshall MF400 cab (my live rig) and it sounds godly. My little 65w Peavey is my practice amp @ home and still couldn't believe how good it sounded through that. |
