New KT150 tubes?

Wolfy ... you'd be quite fortunate if it was JUST the tubes. Unauthorized tube use could cost you the amp.

Who in their right mind would willfully and knowingly abuse their ARC amp by using tubes that weren't sourced from ARC. Shocking!!!

Sorry if I'm pushing into your personal business, but please confess ... how often do you check the bias of the tubes? Do you religiously set the bias at 65 mV??

Just tryin' to be a friend. :)

P.S. Upscale Audio sells the KT-150 for $92 a pop. :)

The "life testing" of 150s has taken so long that it's starting to freak me out..

Wolf -- Look at the bright side. The longer it takes the life testing the longer tube life it has (Duh). I'd consider it a good thing. But I already have the blessing of Octave for my amp. Another thought - Since they now have a new amp that uses the KT150 they must like them. I'm just waiting for my local tube guy (Jim McShane) to sell them.

Confessions: I don't own an ARC amp, but I approve of them generally, and I'm really in no hurry to try 150s so no amps shall be harmed around here. Also, I check my bias on the factory upgraded (I mention that fact to show I care) Jolida 502p I DO own fairly often for no reason other than I have a meter and enjoy risking knuckle burns. I've noticed the LEDs used for bias setting on this amp are very accurate so really the meter is unnecessary, but I do it anyway...500mv per the manual, and the bias on the 120s stays on track really well, even after over 2 years of abuse. According to the Absolute Sound mag I got yesterday, Jolida just put out a new line of power amps with KT150s called "Luxor", and since Jolida hasn't updated their website since 2004 you have to dig through United Home Audio's site to find anything about them. Somebody get those guys a publicist!

Wow...Jolida DID update their site...I stand corrected.
