Any luck for comming weekend?:-)

Hi Maxmad,
The RP tubes brett sent me have uneven output(one is noticeably louder than the other). I`m going to return them to Sophia for inspection and work things out with brett.
The Takasuki tubes(ordered 1 week ago) should arrive in about 2 weeks.

I just received my Takatsuki 300b tubes today(10 days earlier than expected!).I `ll listen tonight after work and will post very early impressions tomorrow.
The packaging and presentation is first rate and the testing measurements are in english(good) but the instruction booklet is japanese only. I`m no tube expert by any means but the appearance and 'feel' of these tubes are really high quality. I`m curious to see how they compare to my beloved Black Treasure tubes which I enjoy so much.I don`t know how many hours are required for burn-in, I guess I`ll soon find out.
Regards,

Great news Charles1dad!

Give them around 100, but I believe they will show you the potentials after several good hours. Come back soon with your impressions.
