winged c 6550c is not good for ref 5se??


I ordered 3 of svetlanan SED winged C 6550c from 'Upscale audio' last week and it was not shipped until today, so i call them to find out what is going on here.
They told me they didnt send it because " This tube is not going to work well with your audio research amp and it will failed almost every time".
Is it right?

For anyone looking to step up from the stock Sovtek whilst keeping their Ref 5SE closer to ARC factory voicing than NOS Tung Sol's I would recommend NOS General Electric 6550.
Thanks,Ill have to try it.Have you tried the 6h30dr.?.The prices seem to be getting very expensive,on ebay.
Hi tsushima1.ive got a winged c and a ge 6550 on the way.It will be interesting to see the difference in sound.
@MisterN, hopefully you managed to source the GE testing to New spec? Should you contract the rolling bug I would also recomend an early 60's solid grey plate, Have Fun .
Excellent,Ill give it a try next year,thanks.They look cool.My new speaker cables arrive in the next few days,Hidiamond d8,Ive never herd them.Ive got a recommendation for you,I bought a revelation audio labs precept pc for my cd player.It was very good,i took it off and plugged it into the power supply distributor,which the cd player and pre,and phonostage are plugged into,now ive got all the good stuff,more dynamics,tone etc going into everything.I replaced the recpticles on the distributor with all furutech gtx rhodium.Im very happy.
