hiya mikirob, funny you should say that but before i bought any of the hifi i did a massive amount of research on amplifiers, cd players, speakers, interconnects and speaker wires. the biggest gamble for me was the amplifier. as much as i read on the yaqin mc100b i still couldn`t be 100% sure it was going to be a goodun being so cheap, but there were so many good write ups i decided to take a gamble. if it turned out to be rubbish at least i could re-sell it for roughly the same price as it was secondhand. in a way i think it was good that the tubes were worn and needed replacing. at first i thought i`d made a major mistake because on first power up the pops and crackles coming out of the speakers made me think it was faulty. i decided to get a pair of the psvane 12ax7`s which transformed the sound and it was then i really started researching all the tubes. i then read about grant fidelity and chose to buy his matched psvane 12ax7`s and yes there was a small difference in sound. i then started researching good places to buy tubes from. all the tubes have been from reputed good sellers with the exception of one set and thats the ge 5751`s that i`m currently waiting on. the kt88-z`s are from a good seller in hong kong and because of the length of time it`s taken i sent them a kind of angry email. they got back to me within a couple of hours and they spent that couple of hours investigating exactly where they are. they also sent proof that they were sent on the day they said they were sent. it`s the customs here in my country is where the hold up has been but thankfully they`ve now been released so i`ll get them this week. it`s just bad luck that we now have snow to contend with! i also had a good chat with karl at karltones in my country. what a great guy he is. he spent almost an hour chatting on the phone giving me all kinds of advice and recommendations. i asked him for advice on the telefunkens and ge 5751`s and recommended both even though he stocked neither but i did buy the jan philips 5751`s off him for a nice cheap price. i make sure i always check out the places i`ve bought the tubes off. i remember reading aricles about being weary where you buy tubes off and at the prices they go for i didn`t want to make any mistakes or at leasr cut down on the mistakes. so far it`s all been good. i wont be buying anymore tubes now once i`ve got the kt88-z`s and the ge 5751`s. i think all the tubes i have are more than good enough quality and as for the yaqin amplifier......i`m stunned! i can`t believe how that amplifier has reacted to all the tube changes i`ve made. i also want to pay tribute to all the rest of the equipment i own too. i think the biggest surprise are the speakers. very cheap and they let me hear all the changes i`ve made not only with the tubes but the wires too. i hope and pray the kt88-z`s will be the last piece of this very special jigsaw. i hope anyone else with this yaqin amplifier reads this and the tube selections i`ve made. even as the sound stands now i can imagine i`ll have to spend an exceedingly much larger amount of money to beat this sound. this amplifier is very special indeed. it actually makes me wonder weather or not to bother changing any capacitors in the amp such is the level and quality of sound but we`ll see. i intend to start a new thread on this very subject once i get the tubes i`m waiting on and once they`re run in. i wholeheartedly agree with you on being careful where you buy the tubes from and i really hope others take note of this too
12ax7 vs 5751
hi all,
i need some advice. i`m very new to tube amplifiers and i`ve been doing some tube rolling.
i currently have a pair of grant fidelity matched psvane 12ax7t`s in my amp which sound fantastic.
what i`d like to know is which are the better tubes, 12ax7`s or 5751 tubes. i`ve been looking at forums and there are folk out there that say 5751 tubes are better than 12ax7 tubes.
can i have your thoughts on this please and also which are the good 5751`s to go for.
i really like the psvanes but if they can be bettered i`d go for it as my next line up of replacement tubes.
my amp is a yaqin mc100b. the tubes i have installed at the moment are.....
2 x psvane 12ax7t`s
2 x brimar 6sn7gty/cv1988`s
2 x sylvania 6sn7gtb`s
4 x electro harmonix kt88eh`s
many thanks in advance guys.
